Parameters

-AllUserConnection: Indicates that the VPN connection specified is in the global phone book.
-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-AuthenticationMethod: Specifies the authentication method to use for the VPN connection. The acceptable values for this parameter are: - PAP - CHAP - MSCHAPv2 - EAP
-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.
-CustomConfiguration: Specifies an XML document that allows vendors to specify custom configuration information.
-DnsSuffix: Specifies the DNS suffix of the VPN connection.
-EapConfigXmlStream: Specifies the contents of the EAP XML configuration file, which includes the EAP method ID.
-EncryptionLevel: Specifies the encryption level for the VPN connection. The acceptable values for this parameter are: - NoEncryption - Optional - Required - Maximum
-Force: Indicates that the pre-shared key (PSK) value is supplied over an insecure channel, if L2TP is used.
-IdleDisconnectSeconds: Specifies the time, in seconds, before closing an idle connection.
-L2tpPsk: Specifies the value of the PSK to be used for L2TP authentication. If this parameter is not specified, a certificate is used for L2TP.
-MachineCertificateEKUFilter: Specifies an array of enhanced key usage (EKU) filters for Internet Key Exchange version 2 (IKEv2) machine certificate selection.
-MachineCertificateIssuerFilter: Specifies the X509 certificate of the issuer filter for IKEv2 machine certificate selection.
-Name (required): Specifies the name of the VPN connection profile.
-PassThru: Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-PlugInApplicationID: Specifies the identifier for a third party application.
-RememberCredential: Indicates that the credentials supplied at the time of first successful connection is stored in the cache, if set to $True.
-ServerAddress: Specifies the address of the remote VPN server to which the client connects. You can specify the address as a fully qualified domain name (FQDN), an IPv4 address, or an IPv6 address.
-ServerList: Specifies an array of VPN servers. The VPN client can connect to these servers.
-SplitTunneling: Indicates whether the cmdlet enables split tunneling for the VPN connection profile. When you enable split tunneling, traffic to destinations outside the intranet does not flow through the VPN tunnel. Specify a value of $True to enable split tunneling.
-ThirdPartyVpn: Indicates that the cmdlet runs for a third party profile.
-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.
-TunnelType: Specifies the type of tunnel used for the VPN connection. The acceptable values for this parameter are: - PPTP - L2TP - SSTP - IKEv2 - Automatic
-UseWinlogonCredential: Indicates whether to use Windows logon credentials. Specify a value of $True to use MSCHAPv2 or EAP-MSCHAPv2 as the authentication method and use Windows logon credentials automatically when connecting with the VPN connection profile.
-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

Example 1: Configure a single VPN connection

Set-VpnConnection -Name "Test1" -ServerAddress "10.1.1.2" -PassThru

This command configures the VPN connection named Test1 to connect to the server with an IP address of 10.1.1.2. By specifying the *PassThru* parameter, you can see the configuration of the VPN connection object. Source: Microsoft, CC BY 4.0; transcript prompt/output removed. This example was not executed.
