Description

The Set-VpnConnection cmdlet changes the configuration settings of an existing VPN connection profile. If the VPN profile specified does not exist, you see an error. If errors occur when you modify the VPN profile, the cmdlet returns the error information.

Examples

Example 1: Configure a single VPN connection

PS C:\> Set-VpnConnection -Name "Test1" -ServerAddress "10.1.1.2" -PassThru
Name                  : Test1

ServerAddress         : 10.1.1.2

AllUserConnection     : False

Guid                  : {4B308E9B-C225-42CB-8158-307193429591}

TunnelType            : Automatic

AuthenticationMethod  : {MsChapv2}

EncryptionLevel       : Required

L2tpIPsecAuth         : Certificate

UseWinlogonCredential : False

EapConfigXmlStream    :   
ConnectionStatus      : Disconnected

NapState              : NotConnected

RememberCredential    : False

SplitTunneling        : False

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.

Example 2: Configure a VPN connection with several settings

PS C:\>Set-VpnConnection -Name "Test3" -AllUserConnection -TunnelType "L2tp" -EncryptionLevel "Optional" -AuthenticationMethod Pap -SplitTunneling $False -RememberCredential $False -PassThru
WARNING: The currently selected encryption level requires EAP or MS-CHAPv2 logon security methods. Data encryption will not occur for Pap or Chap.
Name                  : Test3

ServerAddress         : 10.1.1.1

AllUserConnection     : True

Guid                  : {76746D4E-D72A-467D-A11F-3D4D9075F50D}

TunnelType            : L2tp

AuthenticationMethod  : {Pap}

EncryptionLevel       : Optional

L2tpIPsecAuth         : Certificate

UseWinlogonCredential : False

EapConfigXmlStream    :

ConnectionStatus      : Disconnected

NapState              : NotConnected

RememberCredential    : False

SplitTunneling        : False

This command configures the VPN connection named Test3 and located in the global phone book as follows:

  • The connection is configured to use L2tp as the tunnel type, as specified by the TunnelType parameter
  • The tunnel is using optional encryption, as specified by the EncryptionLevel parameter
  • The authentication method used by the connection is PAP, as specified by the AuthenticationMethod parameter
  • Split tunneling is turned off, as specified by the SplitTunneling parameter, and the value of $False
  • Credential caching is turned off, as specified by the RememberCredential parameter and the value of $False

By specifying the PassThru parameter, you can see the configuration of the VPN connection object.

Example 3: Configure a VPN connection to use a custom EAP configuration

This command stores the result of **New-EapConfiguration** into the variable named $A.
PS C:\>$A = New-EapConfiguration -Tls

This command configures the VPN connection named Test4 in the global phone book to use the custom EAP configuration by: 

-- Specifying the *AuthenticationMethod* parameter with the value EAP
-- Specifying the *EapConfigXmlStream* parameter with the value of the *EapConfigXmlStream* method of the previously created variable.By specifying the *PassThru* parameter, you can see the configuration of the VPN connection object.
PS C:\>Set-VpnConnection -Name "Test4" -AllUserConnection -AuthenticationMethod Eap -EapConfigXmlStream $A.EapConfigXmlStream -PassThru
Name                  : Test4

ServerAddress         : 10.1.1.1

AllUserConnection     : True

Guid                  : {1D423FF3-E3D4-404A-B052-DB9130656D29}

TunnelType            : L2tp

AuthenticationMethod  : {Eap}

EncryptionLevel       : Required

L2tpIPsecAuth         : Psk

UseWinlogonCredential : False

EapConfigXmlStream    : #document

ConnectionStatus      : Disconnected

NapState              : NotConnected

RememberCredential    : True

SplitTunneling        : True

This set of commands first creates a custom EAP configuration, and then configures a VPN connection from the global phone book to use the new custom EAP configuration.

For more information about custom EAP creation, see the New-EapConfiguration cmdlet.

Outputs

Microsoft.Management.Infrastructure.CimInstance#VpnConnection

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.

This cmdlet returns a VpnConnection object that contains the VPN connection configuration settings.
