Detailed Description

The Set-RemoteAccessLoadBalancer cmdlet configures load balancing for a Remote Access (RA) deployment.
-- The InternalDedicatedIPAddress and InternalVirtualIPAddress parameters must be specified unless the server is configured with a single network adapter only.
-- If the use of a third-party external load balancer is Enabled, then Windows network load balancing (NLB) is automatically Disabled, otherwise NLB is Enabled.
-- When load balancing is enabled the IP-HTTPS prefix and the IPv6 prefix for VPN must be of length 59 bits. The IP-HTTPS prefix can be configured using the ClientIPv6Prefix parameter in the Set-DAServer cmdlet.
-- All servers in the cluster share the same RA configuration.

Note: If Windows load balancing is used then the Network Load Balancing role (NLB) needs to be installed prior to using this cmdlet.

Parameters

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete. The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet. For more information about Windows PowerShell® background jobs, see about_Jobs.

Specify the IPv4 address and subnet in the format IP_ADDR/SUBNET. For IPv6 specify the prefix length along with the IP address.
If ISATAP is deployed in the internal network, then at least one of the IP addresses specified in this parameter should be present in the ISATAP name entry in DNS.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

  • None

Outputs

The output type is the type of the objects that the cmdlet emits.

  • Microsoft.Management.Infrastructure.CimInstance#RemoteAccessLoadBalancer

    The Microsoft.Management.Infrastructure.CimInstance object is a wrapper class that displays Windows Management Instrumentation (WMI) objects. The path after the pound sign (#) provides the namespace and class name for the underlying WMI object.
    The RemoteAccessLoadBalancer object consists of the following properties:
    The list of nodes in the cluster and the following properties for each node:
    -- IPv4 or IPv6 address or host name of the node.
    -- The load balancing status of each node.
    -- IPv4 address ranges configured on each node for the VPN static pool address assignment.
    -- Status of third party load balancer: Enabled or Disabled.
    -- The list of internet virtual IP addresses.
    -- The list of internal virtual IP addresses.


Examples

EXAMPLE 1

This example sets the NLB settings with Windows load balancer in edge topology. Therefore the Internet address of the existing DA server located at 131.107.0.2 is promoted to be the internet virtual IP address of the load balanced cluster. In this way, clients can still connect to the same external IP that they connected to without bothering about load balancing.


PS C:\> Set-RemoteAccessLoadBalancer -InternetDedicatedIPAddress "131.107.0.20/255.255.255.0" -InternalDedicatedIPAddress @("3ffe::2/64","10.0.0.2/255.255.255.0") -InternetVirtualIPAddress @("131.107.0.5/255.255.255.0","131.107.0.15/255.255.255.0") -InternalVirtualIPAddress @("3ffe::5/64","10.0.0.5/255.255.255.0") -PassThru
NlbNodeStatus            : edge2.corp.contoso.com 
ThirdPartyLoadBalancer   : Disabled 
InternetVirtualIPAddress : {131.107.0.5/255.255.255.0, 131.107.0.15/255.255.255.0} 
InternalVirtualIPAddress : {3ffe::5/64, 10.0.0.5/255.255.255.0} 

EXAMPLE 2

This example sets the NLB settings with Windows load balancer in single network adapter topology. The corporate network is IPv4 and IPv6 enabled and therefore an array containing the IPv4 and IPv6 addresses for internet VIP and DIP is specified. Since the DA server is behind an edge device, the internet VIPs and DIPs contain corporate network addresses.


PS C:\> Set-RemoteAccessLoadBalancer –InternetDedicatedIPAddress @("10.0.0.2/255.255.255.0","3ffe::2/64") –InternetVirtualIPAddress @("10.0.0.5/255.255.255.0", "3ffe::5/64") –PassThru
NlbNodeStatus            : edge1.corp.contoso.com 
ThirdPartyLoadBalancer    : Disabled 
InternetVirtualIPAddress    : {10.0.0.5/255.255.255.0, 3ffe::5/64} 
InternalVirtualIPAddress    : 

EXAMPLE 3

This example sets the NLB settings using third party load balancer. The administrator will still have to manually configure the NLB device.


PS C:\> Set-RemoteAccessLoadBalancer -InternetDedicatedIPAddress "131.107.0.20/255.255.255.0" -InternalDedicatedIPAddress @("3ffe::2/64","10.0.0.2/255.255.255.0") -InternetVirtualIPAddress @("131.107.0.5/255.255.255.0","131.107.0.15/255.255.255.0") -InternalVirtualIPAddress @("3ffe::5/64","10.0.0.5/255.255.255.0") -PassThru -UseThirdPartyLoadBalancer
NlbNodeStatus            : edge2.corp.contoso.com 
ThirdPartyLoadBalancer   : Enabled 
InternetVirtualIPAddress : {131.107.0.5/255.255.255.0, 131.107.0.15/255.255.255.0} 
InternalVirtualIPAddress : {3ffe::5/64, 10.0.0.5/255.255.255.0} 

EXAMPLE 4

This example disables the external load balancer for a Windows load balanced cluster. The computer will now use the Windows load balancer to balance the load between servers.


PS C:\> Set-RemoteAccessLoadBalancer -ThirdPartyLoadBalancer Disabled –PassThru
NlbNodeStatus            : edge2.corp.contoso.com 
ThirdPartyLoadBalancer   : Disabled 
InternetVirtualIPAddress : {131.107.0.5/255.255.255.0, 131.107.0.15/255.255.255.0} 
InternalVirtualIPAddress : {3ffe::5/64, 10.0.0.5/255.255.255.0} 

EXAMPLE 5

This example enables the external load balancer for a Windows load balanced cluster. The computer will now use the external load balancer to balance the load between servers.


PS C:\> Set-RemoteAccessLoadBalancer –ThirdPartyLoadBalancer Enabled -PassThru
NlbNodeStatus            : edge2.corp.contoso.com 
ThirdPartyLoadBalancer   : Enabled 
InternetVirtualIPAddress : {131.107.0.5/255.255.255.0, 131.107.0.15/255.255.255.0} 
InternalVirtualIPAddress : {3ffe::5/64, 10.0.0.5/255.255.255.0} 

EXAMPLE 6

This example removes the NLB configuration. DA configuration is also removed from all the servers except the one on which the cmdlet is run.


 

PS C:\> Set-RemoteAccessLoadBalancer –Disable
Confirm 
Disabling loadbalancing will disable cluster configuration. Do you want to continue?
