Description

The Set-VpnConnectionIpsecConfiguration cmdlet sets the IPsec parameters of a VPN connection. The settings apply only to IKEv2 and L2TP VPN connections.

Examples

Example 1: Set the IPsec configuration for an IKEv2 tunnel

PS C:\> Add-VpnConnection -Name "Contoso" -ServerAddress 176.16.1.2 -TunnelType "Ikev2"
PS C:\> Set-VpnConnectionIPsecConfiguration -ConnectionName "Contoso" -AuthenticationTransformConstants None -CipherTransformConstants AES256 -EncryptionMethod AES256 -IntegrityCheckMethod SHA384 -PfsGroup None -DHGroup ECP384 -PassThru -Force
AuthenticationTransformConstants : None

CipherTransformConstants         : AES256

DHGroup                          : ECP384

IntegrityCheckMethod             : SHA384

PfsGroup                         : None

EncryptionMethod                 : AES256

This example sets the IPsec configuration for a VPN connection using IKEv2.

The first command uses the Add-VpnConnection cmdlet to add a VPN connection on the server with the address 176.16.1.2. The cmdlet specifies an IKEv2 tunnel.

The second command uses the Set-VpnConnectionIPsecConfiguration cmdlet to set the configuration by using the ConnectionName parameter. The command also specifies values for the CipherTransformConstants, EncryptionMethod, IntegrityCheckMethod, and DHGroup parameters.

Example 2: Set the IPsec configuration for an L2TP tunnel

PS C:\> Add-VpnConnection -Name "Contoso" -ServerAddress 176.16.1.2 -TunnelType "L2tp"
PS C:\> Set-VpnConnectionIPsecConfiguration -ConnectionName "Contoso" -AuthenticationTransformConstants None -CipherTransformConstants AES128 -EncryptionMethod AES128 -IntegrityCheckMethod SHA256 -PfsGroup None -DHGroup ECP256 -PassThru -Force
AuthenticationTransformConstants : None

CipherTransformConstants         : AES128

DHGroup                          : ECP256

IntegrityCheckMethod             : SHA256

PfsGroup                         : None

EncryptionMethod                 : AES128

This example sets the IPsec configuration for an L2TP tunnel.

The first command uses Add-VpnConnection to add a VPN connection on the server with the address 176.16.1.2. The command also specifies an L2TP tunnel.

The second command uses Set-VpnConnectionIPsecConfiguration to set the configuration. The command also specifies values for the CipherTransformConstants, EncryptionMethod, IntegrityCheckMethod, and DHGroup parameters.

Example 3: Set the IPsec configuration for an IKEv2 tunnel with 128-bit data blocks

PS C:\>Add-VpnConnection -Name "Contoso" -ServerAddress 176.16.1.2 -TunnelType "Ikev2"
PS C:\> Set-VpnConnectionIPsecConfiguration -ConnectionName "Contoso" -AuthenticationTransformConstants GCMAES128 -CipherTransformConstants None -EncryptionMethod AES128 -IntegrityCheckMethod SHA256 -PfsGroup None -DHGroup ECP256 -PassThru -Force
AuthenticationTransformConstants : GCMAES128

CipherTransformConstants         : None

DHGroup                          : ECP256

IntegrityCheckMethod             : SHA256

PfsGroup                         : None

EncryptionMethod                 : AES128

This example sets the IPsec configuration for an IKEv2 tunnel with authentication transform constants.

The first command uses Add-VpnConnection to add a VPN connection on the server with the address 176.16.1.2. The cmdlet specifies an IKEv2 tunnel.

The second command uses Set-VpnConnectionIPsecConfiguration to set the configuration. The command also specifies values for the CipherTransformConstants, EncryptionMethod, IntegrityCheckMethod, and DHGroup parameters, as well as specifying a value for the AuthenticationTransformConstants parameter.

Example 4: Set the IPsec configuration for an IKEv2 tunnel with 256-bit data blocks

PS C:\>Add-VpnConnection -Name "Contoso" -ServerAddress 176.16.1.2 -TunnelType "Ikev2"
PS C:\> Set-VpnConnectionIPsecConfiguration -ConnectionName "Contoso" -AuthenticationTransformConstants GCMAES256 -CipherTransformConstants None -EncryptionMethod AES256 -IntegrityCheckMethod SHA384 -PfsGroup None -DHGroup ECP384 -PassThru -Force
AuthenticationTransformConstants : GCMAES256

CipherTransformConstants         : None

DHGroup                          : ECP384

IntegrityCheckMethod             : SHA384

PfsGroup                         : None

EncryptionMethod                 : AES256

This example sets the IPsec configuration for an IKEv2 tunnel, and specifies authentication transform constants.

The first command uses Add-VpnConnection to add a VPN connection on the server with the address 176.16.1.2. The cmdlet specifies an IKEv2 tunnel.

The second command uses Set-VpnConnectionIPsecConfiguration to set the configuration. The command also specifies values for the CipherTransformConstants, EncryptionMethod, IntegrityCheckMethod, and DHGroup parameters, as well as specifying a value for the AuthenticationTransformConstants parameter.
