Parameters

-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-AutoConfigurationScript: Specifies the name of the automatic WPAD configuration script that the specified connection uses.
-AutoDetect: Indicates that proxy settings are automatically detected.
-BypassProxyForLocal: Indicates that the proxy configuration is bypassed for local addresses.
-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.
-Confirm: Prompts you for confirmation before running the cmdlet.
-ConnectionName (required): Specifies the name of a VPN connection profile. To view existing VPN connection profiles, use the Get-VpnConnection cmdlet.
-ExceptionPrefix: Specifies the prefixes for internet addresses for which the proxy is not to be used.
-PassThru: Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-ProxyServer: Specifies the web proxy server IP address and port number. Specify the address and port separated by a colon. For example, 10.0.0.1:8080. If you do not specify the port number, port 80 is used.
-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 VpnClient 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.

Examples
