Set-NetFirewallApplicationFilter

Brian Lich|Last Updated: 3/31/2017

SYNOPSIS

Modifies application filter objects, thereby modifying the program and package conditions of the firewall rules.

SYNTAX

Query (cdxml) (Default)

Set-NetFirewallApplicationFilter [-PolicyStore <String>] [-GPOSession <String>] [-Program <String>]
 [-Package <String>] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-PassThru] [-WhatIf]
 [-Confirm] [<CommonParameters>]

InputObject (cdxml)

Set-NetFirewallApplicationFilter -InputObject <CimInstance[]> [-Program <String>] [-Package <String>]
 [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-PassThru] [-WhatIf] [-Confirm]
 [<CommonParameters>]

DESCRIPTION

The Set-NetFirewallApplicationFilter cmdlet modifies the applications associated with the input firewall rules.

See the Get-NetFirewallApplicationFilter cmdlet for more information on application filters.

To modify the application conditions, two methods can be used starting with the application filters returned by the Get-NetFirewallApplicationFilter cmdlet and optional additional querying.

  • The application filter objects can be piped to the Get-NetFirewallRule cmdlet, which returns the rule objects associated with the filters. These rules are then piped to the Set-NetFirewallRule cmdlet where the application properties can be configured.
  • Alternatively, piping the address filter objects directly to this cmdlet allows the Program and Package parameters of the rules to be specified.

EXAMPLES

EXAMPLE 1

PS C:\>$nfwApplicationFilter = ( Get-FirewallRule -DisplayName "Contoso Messenger" | Get-NetFirewallApplicationFilter )



PS C:\>Set-NetFirewallApplicationFilter -InputObject $nfwApplicationFilter -Program %SystemRoot%\System32\messenger.exe


This cmdlet can be run using only the pipeline.
PS C:\>Get-FirewallRule -DisplayName "Contoso Messenger" | Get-NetFirewallApplicationFilter | Set-NetFirewallApplicationFilter -Program %SystemRoot%\System32\messenger.exe


This cmdlet can be run without using the pipeline.
PS C:\>Set-NetFirewallRule -DisplayName "Contoso Messenger" -Program %SystemRoot%\System32\messenger.exe

This example changes the application path associated with a particular firewall rule.

EXAMPLE 2

PS C:\>$NewPackageSDDL = "S-1-15-2-4292807980-2381230043-3108820062-1451069988-2614848061-670482394-695399705"



PS C:\>$nfwApplicationFilter = (Get-NetFirewallRule -Group Socialite | Get-NetFirewallApplicationFilter )



PS C:\>Set-NetFirewallAddressFilter - InputObject $nfwApplicationFilter -Package $NewPackageSDDL


This cmdlet can be run using only the pipeline.
PS C:\>Get-NetFirewallRule -Group Socialite | Get-NetFirewallApplicationFilter | Set-NetFirewallAddressFilter -Package $NewPackageSDDL

This example modifies the package associated with all related firewall rules for the Socialite Windows Store application.

PARAMETERS

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-GPOSession

Specifies the network GPO from which to retrieve the rules to be modified. This parameter is used in the same way as the PolicyStore parameter. When modifying GPOs in Windows PowerShell®, each change to a GPO requires the entire GPO to be loaded, modified, and saved back. On a busy Domain Controller (DC), this can be a slow and resource-heavy operation. A GPO Session loads a domain GPO onto the local computer and makes all changes in a batch, before saving it back. This reduces the load on the DC and speeds up the Windows PowerShell cmdlets. To load a GPO Session, use the Open-NetGPO cmdlet. To save a GPO Session, use the Save-NetGPO cmdlet.

Type: String
Parameter Sets: Query (cdxml)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-InputObject

Specifies the input object that is used in a pipeline command.

Type: CimInstance[]
Parameter Sets: InputObject (cdxml)
Aliases: 

Required: True
Position: Named
Default value: None
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

-Package

Specifies the Windows Store application to which the firewall rule applies. This parameter is specified as a security identifier (SID). Querying for rules with this parameter can only be performed using filter objects.

Type: String
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-PolicyStore

Specifies the policy store from which to retrieve the rules to be modified. A policy store is a container for firewall and IPsec policy. The acceptable values for this parameter are:

  • PersistentStore: Sometimes called static rules, this store contains the persistent policy for the local computer. This policy is not from GPOs, and has been created manually or programmatically (during application installation) on the computer. Rules created in this store are attached to the ActiveStore and activated on the computer immediately.
  • ActiveStore: This store contains the currently active policy, which is the sum of all policy stores that apply to the computer. This is the resultant set of policy (RSOP) for the local computer (the sum of all GPOs that apply to the computer), and the local stores (the PersistentStore, the static Windows service hardening (WSH), and the configurable WSH). ---- GPOs are also policy stores. Computer GPOs can be specified as follows. ------ -PolicyStore hostname. ---- Active Directory GPOs can be specified as follows. ------ -PolicyStore domain.fqdn.com\GPO_Friendly_Namedomain.fqdn.comGPO_Friendly_Name. ------ Such as the following. -------- -PolicyStore localhost -------- -PolicyStore corp.contoso.com\FirewallPolicy ---- Active Directory GPOs can be created using the New-GPO cmdlet or the Group Policy Management Console.
  • RSOP: This read-only store contains the sum of all GPOs applied to the local computer.
  • SystemDefaults: This read-only store contains the default state of firewall rules that ship with Windows Server® 2012.
  • StaticServiceStore: This read-only store contains all the service restrictions that ship with Windows Server 2012. Optional and product-dependent features are considered part of Windows Server 2012 for the purposes of WFAS.
  • ConfigurableServiceStore: This read-write store contains all the service restrictions that are added for third-party services. In addition, network isolation rules that are created for Windows Store application containers will appear in this policy store. The default value is PersistentStore. The Set-NetFirewallRule cmdlet cannot be used to add an object to a policy store. An object can only be added to a policy store at creation time with the Copy-NetFirewallRule or with the New-NetFirewallRule cmdlet.
Type: String
Parameter Sets: Query (cdxml)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Program

Specifies the path and file name of the program for which the rule allows traffic. This is specified as the full path to an application file. Querying for rules with this parameter can only be performed using filter objects.

Type: String
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type: Int32
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.
