Parameters

-AsJob

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

-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.

-ComputerName

Specifies the IPv4 orIPv6 address, or host name, of the computer on which the VPN server computer specific tasks should be run. If this parameter is specified, then the IPv4 address range is added on that VPN server.

-Confirm

Prompts you for confirmation before running the cmdlet.

-IPAddressRange (required)

Specifies the IP address range that has to be added to the pool. Consists of a start IP and an end IP. The range should not overlap with an existing range.

-PassThru

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

-RoutingDomain

Specifies an ID, as a string, for a routing domain. The ID of a routing domain is a unique user-defined alphanumeric string.

-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.

-WhatIf

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

Prerequisites

Windows with the RemoteAccess module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.

Security considerations

This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.
