Netsh commands for Internet Protocol security

Updated: January 21, 2005

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Netsh commands for Internet Protocol security (IPSec)

The Netsh commands for Internet Protocol security (IPSec) provide an equivalent alternative to the console-based management and diagnostic capabilities provided by the IP Security Policy Management and IP Security Monitor snap-ins available in the Microsoft Management Console (MMC). By using the Netsh commands for IPSec, you can configure and view static or dynamic IPSec main mode settings, quick mode settings, rules, and configuration parameters.

Administering IPSec from the command line is especially useful when you want to:

  • Script IPSec configuration.

  • Extend the security and manageability of IPSec by configuring the following features, which are not available in the IP Security Policy Management snap-in: IPSec diagnostics, default traffic exemptions, strong certificate revocation list (CRL) checking, IKE (Oakley) logging, logging intervals, computer startup security, and computer startup traffic exemptions.

You can run these commands from the Windows Server™ 2003 family command prompt or from the command prompt for the netsh ipsec context. For these commands to work at the Windows Server™ 2003 family command prompt, you must type netsh ipsec before typing commands and parameters as they appear in the syntax below.

Netsh ipsec static mode commands

You can use the netsh ipsec static commands to perform the same management and monitoring tasks that you can perform by using the IP Security Policy Management and IP Security Monitor consoles. By using these commands, you can create, modify, and assign IPSec policies without immediately affecting the configuration of the active IPSec policy.

Netsh ipsec dynamic mode commands

You can use the netsh ipsec dynamic commands to display the active state of IPSec and to immediately affect the configuration of the active IPsec policy. These commands directly configure the security policy database (SPD). Changes that you make to an IPSec policy while using these commands take effect only while the IPSec service is running. If the IPSec service is stopped, the dynamic policy settings are discarded. Although most of these commands take effect immediately, several configuration commands still require you to restart the IPSec service or restart the computer before they take effect. For more information about these commands, see the syntax descriptions for the netsh ipsec dynamic set config commands.

Caution

  • Because the IPSec Policy Agent does not interpret the netsh ipsec dynamic commands, you must be knowledgeable in the application of IKE main mode and quick mode policies to use these commands effectively. Exercise caution when using these commands, because it is possible to create invalid IPSec policy configurations without warning.

Notes

  • The Netsh commands for IPSec can only be used to configure IPSec policies on computers running members of the Windows Server™ 2003 family.

    To use the command line to configure IPSec policies on computers running Windows XP, use Ipseccmd.exe, which is provided on the Windows XPCD, in the \Support\Tools folder. To use the command line to configure IPSec policies on computers running Windows 2000, use Ipsecpol.exe, which is provided with the Windows 2000 Server Resource Kit.

  • For more information about netsh, see Netsh overview and Enter a netsh context.

  • For more information about Netsh commands, see The Netsh Command-Line Utility.

add filter

Adds a filter to the specified filter list.

Syntax

add filter filterlist= srcaddr= dstaddr= [description=][protocol=][mirrored=] [srcmask=][dstmask=][srcport=] [dstport=]

Parameters
filterlist= String
Required. Specifies the name of the filter list to which the filter is added. Each filter defines a set of inbound or outbound network traffic to be secured.

srcaddr={ Me| Any| IPAddress| DNSName| ServerType}
Required. Specifies the source IP address, DNS name, or server type for the IP traffic. You can use WINS, DNS, DHCP, or gateway for ServerType.

dstaddr={ Me| Any| IPAddress| DNSName| ServerType}
Required. Specifies the destination IP address, DNS name, or server type for the IP traffic. You can use WINS, DNS, DHCP, or gateway for ServerType.

[ description=String]
Provides information about the IP filter.

[ protocol={ ANY| ICMP| TCP| UDP| RAW| Integer }]
Specifies the IP protocol if, in addition to addressing information, you want to filter a specific IP protocol. The default value is ANY, meaning all protocols are used for the filter.

[ mirrored={ yes| no}]
Specifies whether to create a mirrored filter. Use yes to create two filters based on the filter settings--one for traffic to the destination and one for traffic from the destination. The default value is yes.

[ srcmask={ Mask| Prefix}]
Specifies the source address subnet mask or the prefix of the packets to be filtered. You can specify a prefix value in the range of 1 through 32. The default value is the mask of 255.255.255.255.

[ dstmask={ Mask| Prefix}
Specifies the destination address subnet mask or the prefix value of the packets to be filtered. You can specify a prefix value in the range of 1 through 32. The default value is the mask of 255.255.255.255.

[ srcport=Port]
Specifies the source port number of the packets to be filtered. This option only applies if you are filtering TCP or UDP packets. If 0 is specified, packets sent from any port are filtered. The default is any.

[ dstport=Port]
Specifies the destination port number of the packets to be filtered. This option only applies if you are filtering TCP or UDP packets. If 0 is specified, packets sent to any port are filtered. The default is any.

Remarks
  • If a filter list does not exist, it is created.

  • Do not create a filter list with the name all. Doing this creates a conflict with the netsh ipsec option to select all IPSec filter lists (for example, delete filterlist all).

  • To filter any packets sent from or to the computer, you can use srcaddr=Me or dstaddr=Me.

  • To filter packets sent from or to any computer, you can use srcaddr=Any or dstaddr=Any.

  • All string parameters are case-sensitive.

add filteraction

Creates a filter action with the specified quick mode security methods.

Syntax

add filteraction name= [description=][qmpfs=][inpass=] [soft=][action=][qmsecmethods=]

Parameters
name= String
Required. Specifies the name of the filter action to be created.

[ description=String]
Provides information about the filter action.

[ qmpfs={ yes| no}]
Specifies whether to enable session key perfect forward secrecy (PFS). If yes is specified, new master key material is renegotiated each time a new session key is required. The default value is no.

[ inpass={ yes| no}]
Specifies whether to allow an incoming packet that matches the configured filter list to be unsecured, but require IPSec-secured communication when replying. The default value is no.

[ soft={ yes| no}]
Specifies whether to fall back to unsecured communication with other computers that do not support IPSec, or when IPSec negotiations with an IPSec-capable computer fail. The default value is no.

[ action={ permit| block| negotiate}]
Specifies whether to permit traffic without negotiating IP security. If permit is specified, traffic is transmitted or received without negotiating or applying IP security. If block is specified, traffic is blocked. If negotiate is specified, IP security is used with the specified list of security methods. The default value is negotiate.

[ qmsecmethods="Neg1Neg2"]
Specifies one or more security methods, separated by spaces and defined by the following format:

{ESP [ConfAlg,AuthAlg]:k/s | AH [HashAlg]:k/s | AH [HashAlg+ESPConfAlg,AuthAlg]:k/s}]

Where:

ConfAlg
Specifies the encryption algorithm. ConfigAlg can be DES (Data Encryption Standard), 3DES, or none.

AuthAlg
Specifies the integrity algorithm. AuthAlg can be MD5 (Message Digest 5), SHA1 (Secure Hash Algorithm 1), or none.

HashAlg
Specifies the hash function. HashAlg can be MD5 (Message Digest 5) or SHA1.

k
Specifies the session key lifetime in kilobytes. After the specified number of kilobytes of data is transferred, a new session key for the quick mode SA is generated. The default value is 100000 kilobytes.

s
Specifies the session key lifetime in seconds. The default value is 3600 seconds.

Remarks
  • Do not create a filter action with the name all. Doing this creates a conflict with the netsh ipsec option to select all IPSec filter actions (for example, delete filteraction all).

  • If action=permit or action=block are specified, and qmsecmethods parameters are specified, the qmsecmethods parameters are not used. In addition, if qmpfs=yes, inpass=yes, or soft=yes are specified, those parameters are also not used.

  • Session key regeneration will start based on whichever interval, seconds or kilobytes, is reached first. If you do not configure new intervals, the default intervals are used.

  • If you do not specify qmsecmethods= (quick mode security methods), the following default values are used:

    • ESP [3DES, SHA1]:100000k/3600s

    • ESP [3DES, MD5]:100000k/3600s

  • The preference order of each quick mode security method is determined by the order in which it was specified in the command.

  • All string parameters are case-sensitive.

add filterlist

Creates an empty filter list with the specified name.

Syntax

add filterlist name= [description=]

Parameters
name= String
Required. Specifies the name of the filter list to be created.

[ description=String]
Provides information about the filter list.

Remarks
  • Do not create a filter list with the name all. Doing this creates a conflict with the netsh ipsec option to select all IPSec filter lists (for example, delete filterlist all).

  • All string parameters are case-sensitive.

add policy

Creates an IPSec policy with the specified name.

Syntax

add policy name= [description=][mmpfs=][qmpermm=] [mmlifetime=][activatedefaultrule=][pollinginterval=][assign=][mmsecmethods=]

Parameters
name= String
Required. Specifies the name of the IPSec policy to be created.

[ description=String]
Provides information about the IPSec policy.

[ mmpfs={ yes| no}]
Specifies whether to enable master key perfect forward secrecy (PFS). If yes is specified, main mode security SAs are reauthenticated and new master key keying material is negotiated each time session key material for a quick mode SA is required. The default value is no.

[ qmpermm=Integer]
Specifies the number of times that master keying material can be used to derive the session key. The default value is 0, meaning an unlimited number of quick mode SAs can be derived from the main mode SA.

[ mmlifetime=Integer]
Specifies the number of minutes after which a new master key will be generated. The default value is 480 minutes.

[ activatedefaultrule={ yes| no}]
Specifies whether to activate the default response rule for this IPSec policy. The default value is yes.

[ pollinginterval=Integer]
Specifies how often IPSec polls for changes to this policy. The default value is 180 minutes.

[ assign={ yes| no}]
Specifies whether to assign this IPSec policy (only one IPSec policy can be assigned) The default value is no.

[ mmsecmethods="SecMeth1SecMeth2"]
Specifies one or more key exchange security methods, separated by spaces and defined by the following format: ConfAlg-HashAlg-GroupNumb, where:

ConfAlg
Specifies the encryption algorithm. ConfAlg can be DES (Data Encryption Standard) or 3DES.

HashAlg
Specifies the hash function. HashAlg can be MD5 (Message Digest 5) or SHA1 (Secure Hash Algorithm 1).

GroupNum
Specifies the Diffie-Hellman group to be used for the base keying material. GroupNumb can be: 1 (low, protects with 768 bits of keying material), 2 (medium, protects with 1024 bits), and 3 (high, protects with 2048 bits).

Remarks
  • Do not create a policy with the name all. Doing this creates a conflict with the netsh ipsec option to select all IPSec policies (for example, delete policy all).

  • Because only one IPSec policy can be assigned, if a policy is currently assigned and you assign a new policy, the currently assigned policy is automatically unassigned.

  • If set store=domain is specified (when the IPSec policy is stored in Active Directory), assign has no effect. To assign a policy to a Group Policy object, you must first create a policy by using the add policy command, and then use the set store command.

  • If mmpfs=yes is specified (master key PFS is enabled), by default qmperm is set to 1 and not configurable, because each new session will cause the master key keying material to be renegotiated.

  • If you do not specify mmsecmethods= (key exchange security methods), the following default values are used:

    • 3DES-SHA1-2

    • 3DES-MD5-2

    • 3DES-SHA1-3

  • IPSec peers must have at least one common key exchange security method (one that uses the same settings) or negotiations will fail.

  • If the number of quick mode negotiations will exceed the value set for the number of quick mode negotiations per main mode negotiation during the main mode lifetime, a new main mode negotiation occurs.

  • All string parameters are case-sensitive.

add rule

Creates a rule that links the specified IPSec policy, filter list, and filter action with the specified authentication methods.

Syntax

add rule name= policy= filterlist= filteraction=[tunnel=][conntype=] [activate=][description=][kerberos=][psk=][rootca=]

Parameters
name= String
Required. Specifies the name of the IPSec rule to be created.

policy= String
Required. Specifies the name of the IPSec policy that contains this rule.

filterlist= String
Required. Specifies the name of the IP filter list for this rule.

filteraction= String
Required. Specifies the name of the filter action for this rule.

[ tunnel={ IPAddress| DNSName}]
Specifies the IP address or DNS name of the tunnel endpoint for tunnel mode. By default, this option is not specified and transport mode is used.

[ conntype={ lan| dialup| all}]
Specifies whether the rule applies only to remote access or dial-up connections or to local area network (LAN) connections, or to all connections. The default value is all.

[ activate={ yes | no}]
Specifies whether to activate this rule for the specified IPSec policy. The default value is yes.

[ description=String]
Provides information about the rule.

[ kerberos={ yes | no}]
Specifies whether to use the Kerberos V5 protocol as an authentication method.

[ psk=String]
Specifies the string of characters to use for the preshared key, if a preshared key is used as an authentication method.

[ rootca="Stringcertmap:{ yes| no} excludecaname:{ yes| no} "]
Specifies certificate authentication options, where:

String
Specifies the distinguished name of the certificate, if a certificate is used as an authentication method.

certmap:{ yes| no}
Specifies whether to enable certificate-to-account mapping. You can enable certificate-to-account mapping to verify that the certificate is being used by a trusted computer.

excludecaname:{ yes| no}
Specifies whether to exclude from the certificate request the list of trusted root CA names from which a certificate is accepted.

Remarks
  • Do not create a rule with the name all. Doing this creates a conflict with the netsh ipsec option to select all IPSec rules (for example, delete rule all).

  • You can only use Kerberos V5 authentication or certificate-to-account mapping for computers that are members of an Active Directory domain.

  • Although you can use only one preshared key for authentication, you can use multiple certificates by specifying the rootca parameter once, for each certificate you want to use.

  • All certificate authentication parameters must be contained within quotation marks. Embedded quotation marks must be replaced by a backslash followed by an apostrophe (\').

  • All string parameters are case-sensitive.

  • The preference order of each authentication method is determined by the order in which it was specified in the command.

  • If no authentication methods are specified, dynamic defaults are used. By default, IPSec policies use Kerberos V5 authentication. If the computer has a computer certificate, any root CA to which the computer certificate chains is also used for authentication.

  • If excludecaname:yes is specified, the list of trusted root CAs is not sent as part of the certificate request, which prevents the potential disclosure of sensitive information about the trust relationships of a computer. To enhance security for computers connected to the Internet, specify this option.

  • The use of preshared key authentication is not recommended because it is a relatively weak authentication method. In addition, preshared keys are stored in plaintext.

  • IPSec peers must have at least one common authentication method or communication will fail.

delete all

  • You can only use Kerberos V5 authentication or certificate-to-account mapping for computers that are members of an Active Directory domain.

  • Although you can use only one preshared key for authentication, you can use multiple certificates by specifying the rootca parameter once, for each certificate you want to use.

  • All certificate authentication parameters must be contained within quotation marks. Embedded quotation marks must be replaced by a backslash followed by an apostrophe (\').

  • All string parameters are case-sensitive.

  • The preference order of each authentication method is determined by the order in which it was specified in the command.

  • If no authentication methods are specified, dynamic defaults are used. By default, IPSec policies use Kerberos V5 authentication. If the computer has a computer certificate, any root CA to which the computer certificate chains is also used for authentication.

  • If excludecaname:yes is specified, the list of trusted root CAs is not sent as part of the certificate request, which prevents the potential disclosure of sensitive information about the trust relationships of a computer. To enhance security for computers connected to the Internet, specify this option.

  • The use of preshared key authentication is not recommended because it is a relatively weak authentication method. In addition, preshared keys are stored in plaintext.

  • IPSec peers must have at least one common authentication method or communication will fail.

  • Modifying authentication methods will overwrite all previous authentication methods, even if the previous authentication methods were different. For example, if kerberos=yes and psk=yes were previously specified, and then you specify kerberos=no, the psk=yes parameter will also be overwritten, and preshared key authentication will no longer be used.

  • ConfAlg and AuthAlg cannot both be set to none.

set filteraction

Modifies a filter action.

Syntax

set filteraction name= | guid=[newname=] [description=][qmpfs=][inpass=] [soft=][action=][qmsecmethods=]

[ gponame=String]
Specifies the name of the Group Policy object to which the IPSec policy is assigned. This parameter is only applicable if you are configuring policy for a computer that is an Active Directory domain member.

[ mmsecmethods="SecMeth1SecMeth2"]
Specifies one or more key exchange security methods, separated by spaces and defined by the following format: ConfAlg-HashAlg-GroupNumb, where:

ConfAlg
Specifies the encryption algorithm. ConfAlg can be DES (Data Encryption Standard) or 3DES.

HashAlg
Specifies the hash function. HashAlg can be MD5 (Message Digest 5) or SHA1 (Secure Hash Algorithm 1).

GroupNum
Specifies the Diffie-Hellman group to be used for the base keying material. GroupNumb can be: 1 (low, protects with 768 bits of keying material), 2 (medium, protects with 1024 bits), and 3 (high, protects with 2048 bits).

Remarks
  • If you specify a new name for the policy, do not use the name all. Doing this creates a conflict with the netsh ipsec option to select all IPSec policies (for example, delete policy all).

  • If set store=domain is specified (when the IPSec policy is stored in Active Directory), assign will have no effect.

  • If mmpfs=yes is specified (master key PFS is enabled), by default qmperm is set to 1 and not configurable, because each new session will cause the master key keying material to be renegotiated.

  • IPSec peers must have at least one common key exchange security method (one that uses the same settings) or negotiations will fail.

  • You can only specify a Group Policy object name if set store=domain.

  • All string parameters are case-sensitive.

set rule

Modifies a rule in an IPSec policy.

Syntax

set rule name= | ID=policy= [newname=][description=][filterlist=] [filteraction=] [tunnel=][conntype=] [activate=][kerberos=][psk=][rootca=]

Parameters
name= String| ID=Integer
Required. Specifies the name or ID (the number identifying the position of the rule in the policy rule list) of the rule to modify.

policy= String
Required. Specifies the name of the IPSec policy that contains this rule.

[ newname=String]
Specifies the new name of the rule.

[ description=String]
Provides information about the rule.

[ filterlist=String]
Specifies the name of the IP filter list for this rule.

[ filteraction=String]
Specifies the name of the filter action for this rule.

[ tunnel={ IPAddress| DNSName}]
Specifies the IP address or DNS name of the tunnel endpoint for tunnel mode.

[ conntype={ lan| dialup| all}]
Specifies whether the rule applies only to remote access or dial-up connections or to local area network (LAN) connections, or to all connections.

[ activate={ yes | no}]
Specifies whether to activate this rule for the specified IPSec policy.

[ kerberos={ yes | no}]
Specifies whether to use the Kerberos V5 protocol as an authentication method.

[ psk=String]
Specifies the string of characters to use for the preshared key, if a preshared key is used as an authentication method.

[ rootca="Stringcertmap:{ yes| no} excludecaname:{ yes| no} "]
Specifies certificate authentication options, where:

String
Specifies the distinguished name of the certificate, if a certificate is used as an authentication method.

certmap:{ yes| no}
Specifies whether to enable certificate-to-account mapping. You can enable certificate-to-account mapping to verify that the certificate is being used by a trusted computer.

excludecaname:{ yes| no}
Specifies whether to exclude from the certificate request the list of trusted root CA names from which a certificate is accepted.

Remarks
  • You can only use Kerberos V5 authentication or certificate-to-account mapping for computers that are members of an Active Directory domain.

  • Although you can use only one preshared key for authentication, you can use multiple certificates by specifying the rootca parameter once, for each certificate you want to use.

  • All certificate authentication parameters must be contained within quotation marks. Embedded quotation marks must be replaced by a backslash followed by an apostrophe (\').

  • All string parameters are case-sensitive.

  • The preference order of each authentication method is determined by the order in which it was specified in the command.

  • If no authentication methods are specified, dynamic defaults are used. By default, IPSec policies use Kerberos V5 authentication. If the computer has a computer certificate, any root CA to which the computer certificate chains is also used for authentication.

  • If excludecaname:yes is specified, the list of trusted root CAs is not sent as part of the certificate request, which prevents the potential disclosure of sensitive information about the trust relationships of a computer. To enhance security for computers connected to the Internet, specify this option.

  • The use of preshared key authentication is not recommended because it is a relatively weak authentication method. In addition, preshared keys are stored in plaintext.

  • IPSec peers must have at least one common authentication method or communication will fail.

  • Modifying authentication methods will overwrite all previous authentication methods, even if the previous authentication methods were different. For example, if kerberos=yes and psk=yes were previously specified, and then you specify kerberos=no, the psk=yes parameter will also be overwritten, and preshared key authentication will no longer be used.

set store

Sets the current IPSec policy storage location.

Syntax

set store location= [domain=]

Parameters
location={ local| persistent| domain}
Required. Specifies the storage location for the IPSec policy.

[ domain=]
Specifies the name of the domain where the IPSec policy is stored, if the policy is stored in Active Directory (when location=domain is specified).

Remarks
  • The set store command only works from within the netsh environment, that is:

    • If you run this command from the command prompt for the netsh ipsec context).

    • If you run a batch file by using the netsh.exe command.

  • The persistent store contains IPSec policies that can be assigned to secure this computer at start up, before the local policy or domain-based policy is applied. A persistent IPSec policy provides security in the event of a failure because it remains in effect whether the local policy or domain-based policy is applied or not (for example, an IPSec policy might not be applied if it is corrupted). For enhanced security, it is recommended that you create and assign a persistent policy.

  • The local store contains IPSec policies that can be assigned to secure this computer. If a domain policy is available, the domain policy is applied instead of the local policy.

  • The domain store contains IPSec policies that can be assigned to secure groups of computers in a domain.

  • It is recommended that the persistent policy be the most restrictive of all policies. Domain policies and local policies should complement persistent policies.

  • Use the set machine command to configure a remote computer.

  • All string parameters are case-sensitive.

Remarks
  • Do not create a main mode policy with the name all. Doing this creates a conflict with the netsh ipsec option to select all IPSec main mode policies (for example, delete mmpolicy all).

  • If the number of quick mode negotiations will exceed the value set for the number of quick mode negotiations per main mode negotiation during the main mode lifetime, a new main mode negotiation occurs.

  • If you do not specify mmsecmethods= (key exchange security methods), the following default values are used:

    • 3DES-SHA1-2

    • 3DES-MD5-2

    • 3DES-SHA1-3

  • IPSec peers must have at least one common key exchange security method (one that uses the same settings) or negotiations will fail.

  • All string parameters are case-sensitive.

add qmpolicy

  • ConfAlg and AuthAlg cannot both be set to none.

  • IPSec peers must have the same pfsgroup enabled (that is, both peers must use the same Diffie-Hellman group for session key PFS), or communication will fail.

  • For enhanced security, do not use Diffie-Hellman Group 1. For maximum security, use Group 2048 whenever possible. Use Group 2 when required for interoperability with Windows 2000 and Windows XP.

  • All string parameters are case-sensitive.

add rule

Creates an IPSec rule with the specified main mode policy and quick mode policy and adds it to the SPD.

Syntax

add rule srcaddr= dstaddr= mmpolicy=[qmpolicy=][protocol=][srcport=][dstport=][mirrored=][conntype=][actioninbound=][actionoutbound=][srcmask=][dstmask=][tunneldstaddress=][kerberos=][psk=][rootca=]

[ protocol={ ANY| ICMP| TCP| UDP| RAW| Integer }]
Specifies the IP protocol if, in addition to address information, you want to filter a specific IP protocol. The default value is ANY, meaning all protocols are used for the filter.

[ srcport=Port]
Specifies the source port number of the packets to be filtered. This option only applies if you are filtering TCP or UDP packets. If 0 is specified, packets sent from any port are filtered. The default is any.

[ dstport=Port]
Specifies the destination port number of the packets to be filtered. This option only applies if you are filtering TCP or UDP packets. If 0 is specified, packets sent to any port are filtered. The default is any.

[ mirrored={ yes| no}]
Specifies whether to create a mirrored filter. Use yes to create two filters based on the filter settings, one for traffic to the destination and one for traffic from the destination. The default value is yes.

[ conntype={ lan| dialup| all}]
Specifies whether the rule applies only to remote access or dial-up connections or to local area network (LAN) connections, or to all connections. The default value is all.

[ actioninbound={ permit| block| negotiate}]
Specifies the action that IPSec is required to take for inbound traffic. If permit is specified, traffic is received without negotiating or applying IP security. If block is specified, traffic is blocked. If negotiate is specified, IP security is used, with the list of security methods specified in the main mode and quick mode policies. The default value is negotiate.

[ actionoutbound={ permit| block| negotiate}]
Specifies the action that IPSec is required to take for outbound traffic. If permit is specified, traffic is sent without negotiating or applying IP security. If block is specified, traffic is blocked. If negotiate is specified, IP security is used, with the list of security methods specified in the main mode and quick mode policies. The default value is negotiate.

[ srcmask={ Mask| Prefix}]

[ kerberos={ yes | no}]
Specifies whether to use the Kerberos V5 protocol as an authentication method.

[ psk=String]
Specifies the string of characters to use for the preshared key, if a preshared key is used as an authentication method.

[ rootca="Stringcertmap:{ yes| no} excludecaname:{ yes| no} "]
Specifies certificate authentication options, where:

String
Specifies the distinguished name of the certificate, if a certificate is used as an authentication method.

certmap:{ yes| no}
Specifies whether to enable certificate-to-account mapping. You can enable certificate-to-account mapping to verify that the certificate is being used by a trusted computer.

excludecaname:{ yes| no}
Specifies whether to exclude from the certificate request the list of trusted root CA names from which a certificate is accepted.

Remarks
  • Do not create a rule with the name all. Doing this creates a conflict with the netsh ipsec option to select all IPSec rules (for example, delete rule all).

  • If the filter action for both inbound and outbound traffic (actioninbound and actionoutbound) are set to Permit or Block, a quick mode filter is not required.

  • If a tunnel rule is specified, mirror should be set to no (by default, mirror is set to yes). For IPSec tunnels, you must create two rules--one rule describes the traffic to be sent through the tunnel (outbound traffic) and the other describes the traffic to be received through the tunnel (inbound). Next, create two rules that use the inbound and outbound filter lists in your policy.

  • To filter any packets sent from or to the computer, you can use srcaddr=Me or dstaddr=Me.

  • To filter packets sent from or to any computer, you can use srcaddr=Any or dstaddr=Any.

  • You can only use Kerberos V5 authentication or certificate-to-account mapping for computers that are members of an Active Directory domain.

  • Although you can use only one preshared key for authentication, you can use multiple certificates by specifying the rootca parameter once, for each certificate you want to use.

  • All certificate authentication parameters must be contained within quotation marks. Embedded quotation marks must be replaced by a backslash followed by an apostrophe (\').

  • All string parameters are case-sensitive.

  • The preference order of each authentication method is determined by the order in which it was specified in the command.

  • If no authentication methods are specified, dynamic defaults are used. By default, IPSec policies use Kerberos V5 authentication. If the computer has a computer certificate, any root CA to which the computer certificate chains is also used for authentication.

  • If excludecaname:yes is specified, the list of trusted root CAs is not sent as part of the certificate request, which prevents the potential disclosure of sensitive information about the trust relationships of a computer. To enhance security for computers connected to the Internet, specify this option.

  • The use of preshared key authentication is not recommended because it is a relatively weak authentication method. In addition, preshared keys are stored in plaintext.

  • IPSec peers must have at least one common authentication method or communication will fail.

[ tunneldstaddress={ IPAddress| DNSName}]
Specifies whether the traffic is tunneled and, if it is, the IP address or DNS name of the tunnel destination (the computer or gateway on the other side of the tunnel).

Remarks
  • To filter any packets sent from or to the computer, you can use srcaddr=Me or dstaddr=Me.

  • To filter packets sent from or to any computer, you can use srcaddr=Any or dstaddr=Any.

set config

Creates or modifies the following IPSec settings: IPSec diagnostics, default traffic exemptions, strong certificate revocation list (CRL) checking, IKE (Oakley) logging, logging intervals, computer startup security, and computer startup traffic exemptions.

Syntax

set config [property=] [value=]

Parameters
[ property=]{ ipsecdiagnostics value=| ipsecexempt value=| ipsecloginterval value=| ikelogging value=| strongcrlcheck value=| bootmode value=| bootexemptions value=}
Required. Specifies the name of the IPSec setting to be created or modified and a value for the setting,

where:

ipsecdiagnostics value={ 0| 1| 2| 3| 4| 5| 6| 7}
Specifies whether to enable IPSec diagnostic logging and, if so, which level of logging to provide. The default value is 0, meaning that logging is disabled. If you change the value for this setting, you must restart the computer for the new value to take effect.

You can specify other values as follows, to enable different levels of logging:

  • When 1 is specified, bad SPI packets (the total number of packets for which the Security Parameters Index or SPI was incorrect), IKE negotiation failures, IPSec processing failures, packets received with invalid packet syntax, and other errors are recorded in the System log. Unauthenticated hashes (with the exception of the "Clear text received when should have been secured" event) are logged as well.

  • When 2 is specified, inbound per-packet drop events are recorded in the System log.

  • When 3 is specified, level 1 and level 2 logging are performed. In addition, unexpected clear text events (packets that are sent or received in plaintext) are also recorded.

  • When 4 is specified, outbound per-packet drop events are recorded in the System log.

  • When 5 is specified, level 1 and level 4 logging are performed.

  • When 6 is specified, level 2 and level 4 logging are performed.

  • When 7 specified, all levels of logging are performed.

ipsecexempt value={ 0| 1| 2| 3}
Specifies whether to modify the default IPSec traffic exemption (traffic that is not matched against IPSec filters but is still permitted). The default value is 3, meaning that only IKE traffic is exempted from IPSec filtering. If you change the value for this setting, you must restart the computer for the new value to take effect.

You can specify other values as follows:

  • If 0 is specified, multicast, broadcast, RSVP, Kerberos, and IKE traffic is exempted from IPSec filtering.

  • If 1 is specified, Kerberos and RSVP traffic is not exempted from IPSec filtering (multicast, broadcast, and IKE traffic is exempted).

  • If 2 is specified, multicast and broadcast traffic is not exempted from IPSec filtering (RSVP, Kerberos, and IKE traffic is exempted).

ipsecloginterval value={ Integer}
Specifies the interval, in seconds, after which IPSec event logs are sent to the System log. For Integer, valid values range from 60 through 86400. The default value is 3600. If you change the value for this setting, you must restart the computer for the new value to take effect.

ikelogging value={ 0| 1}
Specifies whether to enable IKE (Oakley) logging, to generate details about the SA establishment process. The default value is 0, meaning that IKE logging is disabled.

strongcrlcheck value={ 0| 1| 2}
Specifies the level of CRL checking to use. If 0 is specified, CRL checking is disabled. If 1 is specified, standard CRL checking is used, and certificate validation fails only if the certificate is determined to be revoked. If 2 is specified, strong CRL checking is used, and certificate validation fails if any CRL check error occurs. The default value is 1.

bootmode value={ stateful| block| permit}
Specifies the action that IPSec is required to take when the computer starts. If stateful is specified, only the following traffic is permitted during computer startup: outbound traffic initiated by the computer during startup, inbound traffic that is sent in response to the outbound traffic, and DHCP traffic. If block is specified, all inbound and outbound traffic is blocked until a local IPSec policy or a domain-based IPSec policy is applied. If permit is specified, all traffic is transmitted and received. The default value is stateful. If you use either stateful filtering or if you specify that traffic be blocked during computer startup, you can also use the bootexemptions parameter to specify traffic types that you want to exempt from IPSec filtering during computer startup.

If you change the value for this setting, you must restart the computer for the new value to take effect.

bootexemptions value= Exemption1Exemption2
Specifies one or more IPSec traffic exemptions from startup security, separated by spaces and defined by the following format for TCP and UDP traffic: protocol:srcport:dstport:direction and the following format for non-TCP/UDP traffic: protocol:direction, where:

protocol ={ ICMP| TCP| UDP| RAW| Integer }
Specifies the IP protocol type to exempt from IPSec filtering during computer startup.

srcport = Port
Specifies the source port number of the packets to exempt from IPSec filtering during computer startup. A value of 0 means that any source port is exempted.

dstport = Port
Specifies the destination port number of the packets to exempt from IPSec filtering during computer startup. A value of 0 means that any destination port is exempted.

direction ={ inbound | outbound}
Specifies the direction of the traffic to exempt from IPSec filtering during computer startup.

Remarks
  • Use strong CRL checking (set property=strongcrlcheck value=2) if the CRL distribution point must be reachable on the network and certificates can only be validated if no CRL check error occurs.

  • IPSec can only negotiate security associations for Kerberos traffic if your IPSec policy does not use Kerberos as the authentication method. If Kerberos is required for authentication, you must exempt Kerberos traffic by using the ipsecexempt parameter.

  • In Windows 2000 and Windows XP, by default, all broadcast, multicast, Internet Key Exchange (IKE), Kerberos, and Resource Reservation Protocol (RSVP) traffic was exempted from IPSec filtering. In the Windows Server™ 2003 family, only IKE traffic is exempted from IPSec filtering by default. All other traffic types are now matched against IPSec filters, and you can configure block or permit filter actions specifically for multicast and broadcast traffic (IPSec does not negotiate security associations for multicast and broadcast traffic).

    As a result of this change in default behavior for IPSec, you should verify the behavior of IPSec policies designed for Windows 2000 or Windows XPand determine whether to configure explicit permit filters to permit specific traffic types. To restore the default behavior of Windows 2000 and Windows XPfor IPSec policies, edit the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IPSec. Add a new DWORD value named NoDefaultExempt and assign to it a value of 0. For more information about adding values to registry keys, see Add a value to a registry key entry.

Caution

  • Incorrectly editing the registry may severely damage your system. Before making changes to the registry, you should back up any valued data on the computer.

  • Modifying IPSec traffic exemptions from startup security (that is, modifying the bootexemptions= parameter) will overwrite all previous exemptions from startup security.

set mmpolicy

Syntax

set mmpolicy name= [qmperm=][mmlifetime=][softsaexpirationtime=][mmsecmethods=]

Parameters
name= String
Required. Specifies the name of the IPSec main mode policy to modify.

[ qmpermm=Integer]
Specifies the number of times that master keying material is used to derive the session key. A value of 0 means that an unlimited number of quick mode SAs can be derived from the main mode SA.

[ mmsecmethods="SecMeth1SecMeth2"]
Specifies one or more key exchange security methods, separated by spaces and defined by the format ConfAlg-HashAlg-GroupNumb, where:

ConfAlg
Specifies the encryption algorithm. ConfAlg can be DES or 3DES.

HashAlg
Specifies the hash function. HashAlg can be MD5 or SHA1.

GroupNum
Specifies the Diffie-Hellman group to be used for the base keying material. GroupNumb can be: 1 (low, protects with 768 bits of keying material), 2 (medium, protects with 1024 bits), and 3 (high, protects with 2048 bits).

Remarks
  • IPSec peers must have at least one common key exchange security method (one that uses the same settings) or negotiations will fail.

  • If the number of quick mode negotiations will exceed the value set for the number of quick mode negotiations per main mode negotiation during the main mode lifetime, a new main mode negotiation occurs.

  • All string parameters are case-sensitive.

set qmpolicy

Modifies an IPSec quick mode policy and writes the changes to the SPD.

Syntax

set qmpolicy name= [soft=][pfsgroup=][qmsecmethods=]

Parameters
name= String
Required. Specifies the name of the IPSec quick mode policy to modify.

[ soft={ yes| no}]
Specifies whether to fall back to unsecured communications with other computers that do not support IPSec, or when IPSec negotiations with an IPSec-capable computer fail.

[ pfsgroup={ grp1| grp2| grp3| grpmm| nopfs}]
Specifies the Diffie-Hellman group to use for session key PFS. If grp1 is specified, Group 1 (low) is used. If grp2 is specified, Group 2 (medium) is used. If grp3 is specified, Group 2048 (high) is used. If grpmm is specified, the group value is taken from the current main mode settings. A value of nopfs means that session key PFS is disabled.

[ qmsecmethods="Neg1Neg2"]
Specifies one or more security methods, separated by spaces and defined by the following format:{ESP [ConfAlg,AuthAlg]:k/s | AH [HashAlg]:k/s | AH [HashAlg+ESPConfAlg,AuthAlg]:k/s}]

s
Specifies the session key lifetime in seconds. The default value is 3600 seconds.

Remarks
  • The preference order of each quick mode security method is determined by the order in which it was specified in the command.

  • IPSec peers must have the same pfsgroup enabled (that is, both peers must use the same Diffie-Hellman group for session key PFS), or communication will fail.

  • For enhanced security, do not use Diffie-Hellman Group 1. For maximum security, use Group 2048 whenever possible. Use Group 2 when required for interoperability with Windows 2000 and Windows XP.

  • All string parameters are case-sensitive.

set rule

Modifies an IPSec rule that defines a set of filters and writes the changes to the SPD.

Parameters
srcaddr={ Me| Any| IPAddress| DNSName| ServerType}
Required. Specifies the source IP address, DNS name, or server type for the IP traffic. You can use WINS, DNS, DHCP, or gateway for ServerType.

dstaddr={ Me| Any| IPAddress| DNSName| ServerType}
Required. Specifies the destination IP address, DNS name, or server type for the IP traffic. You can use WINS, DNS, DHCP, or gateway for ServerType.

protocol={ ANY| ICMP| TCP| UDP| RAW| Integer }
Required. Specifies the IP protocol used for the filter.

srcport= Port
Required. Specifies the source port number of the packets being filtered. This option only applies if you are filtering TCP or UDP packets. A value of 0 matches filters set to a source port of 0 or any.

dstport= Port
Required. Specifies the destination port number of the packets being filtered. This option only applies if you are filtering TCP or UDP packets. A value of 0 matches filters set to a destination port of 0 or any.

mirrored={ yes| no}
Required. Specifies whether the rule was created with mirrored filters.

conntype={ lan| dialup| all}
Required. Specifies whether the rule applies only to remote access or dial-up connections or to local area network (LAN) connections, or to all connections.

[ srcmask={ Mask| Prefix}]
Specifies the source address subnet mask or the prefix of the packets being filtered. You can specify a prefix value in the range of 1 through 32. The default value is the mask of 255.255.255.255.

[ dstmask={ Mask| Prefix}]
Specifies the destination address subnet mask or the prefix value of the packets being filtered. You can specify a prefix value in the range of 1 through 32. The default value is the mask of 255.255.255.255.

[ tunneldstaddress={ IPAddress| DNSName}]
Specifies whether the traffic is tunneled and, if it is, the IP address or DNS name of the tunnel destination (the computer or gateway on the other side of the tunnel).

[ mmpolicy=String]
Specifies the name of the main mode policy.

[ qmpolicy=String]
Specifies the name of the quick mode policy.

[ actioninbound={ permit| block| negotiate}]
Specifies the action that IPSec is required to take for inbound traffic. If permit is specified, traffic is received without negotiating or applying IP security. If block is specified, traffic is blocked. If negotiate is specified, IP security is used, with the list of security methods specified in the main mode and quick mode policies.

[ actionoutbound={ permit| block| negotiate}]
Specifies the action that IPSec is required to take for outbound traffic. If permit is specified, traffic is sent without negotiating or applying IP security. If block is specified, traffic is blocked. If negotiate is specified, IP security is used, with the list of security methods specified in the main mode and quick mode policies.

[ kerberos={ yes | no}]
Specifies whether to use the Kerberos V5 protocol as an authentication method.

[ psk=String]
Specifies the string of characters to use for the preshared key, if a preshared key is used as an authentication method.

[ rootca="Stringcertmap:{ yes| no} excludecaname:{ yes| no} "]
Specifies certificate authentication options, where:

String
Specifies the distinguished name of the certificate, if a certificate is used as an authentication method.

certmap:{ yes| no}
Specifies whether to enable certificate-to-account mapping. You can enable certificate-to-account mapping to verify that the certificate is being used by a trusted computer.

excludecaname:{ yes| no}
Specifies whether to exclude from the certificate request the list of trusted root CA names from which a certificate is accepted.

Remarks
  • You can modify the following parameters: mmpolicy=, qmpolicy=, actioninbound=, and actionoutbound=. All other parameters are used to identify the rule that you want to modify, and therefore they cannot be modified.

  • If the filter action for both inbound and outbound traffic (actioninbound and actionoutbound) are set to Permit or Block, a quick mode filter is not required.

  • If a tunnel rule is specified, mirror should be set to no (by default, mirror is set to yes). For IPSec tunnels, you must create two rules: one rule describes the traffic to be sent through the tunnel (outbound traffic) and the other describes the traffic to be received through the tunnel (inbound). Next, create two rules that use the inbound and outbound filter lists in your policy.

  • To filter any packets sent from or to the computer, you can use srcaddr=Me or dstaddr=Me.

  • To filter packets sent from or to any computer, you can use srcaddr=Any or dstaddr=Any.

  • You can only use Kerberos V5 authentication or certificate-to-account mapping for computers that are members of an Active Directory domain.

  • Although you can use only one preshared key for authentication, you can use multiple certificates by specifying the rootca parameter once, for each certificate you want to use.

  • All certificate authentication parameters must be contained within quotation marks. Embedded quotation marks must be replaced by a backslash followed by an apostrophe (\').

  • All string parameters are case-sensitive.

  • The preference order of each authentication method is determined by the order in which it was specified in the command.

  • If no authentication methods are specified, dynamic defaults are used. By default, IPSec policies use Kerberos V5 authentication. If the computer has a computer certificate, any root CA to which the computer certificate chains is also used for authentication.

  • If excludecaname:yes is specified, the list of trusted root CAs is not sent as part of the certificate request, which prevents the potential disclosure of sensitive information about the trust relationships of a computer. To enhance security for computers connected to the Internet, specify this option.

  • The use of preshared key authentication is not recommended because it is a relatively weak authentication method. In addition, preshared keys are stored in plaintext.

  • IPSec peers must have at least one common authentication method or communication will fail.

  • Modifying authentication methods will overwrite all previous authentication methods, even if the previous authentication methods were different. For example, if kerberos=yes and psk=yes were previously specified, and then you specify kerberos=no, the psk=yes parameter will also be overwritten, and preshared key authentication will no longer be used.
