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.

EXAMPLES

EXAMPLE 1

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}

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.

EXAMPLE 2

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    :

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.

EXAMPLE 3

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}

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

EXAMPLE 4

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}

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.

EXAMPLE 5

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}

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.

EXAMPLE 6

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

[Y] Yes  [N] No  [S] Suspend  [?] Help (default is ꞌYꞌ): Y

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