Windows 11 L2TP and IPSEC: Where to set the IpSec group

Question

First of all:

• I know : L2TP and IPSEC from Windows XP: Where do I put the IPSEC group name? exists, but the answer is incorrect and is not working on Windows 11 (please do not duplicate this topic by linking that one, it's 13 years old).
• And: L2TP and IPSEC from Windows 11: Where do I put the IPSEC group name? was closed pointing on the first topic without addressing the question as well. (@Jan Janiszewski)

We need to connect to an already setup VPN using IPSec Id / Group name:

VPN Data:

• VPN type: "IPSec" or "IPSec Xauth PSK"
• Name / Description: Individualized name for the connection
• Server address / Server: 45.123.123.12
• IPSec ID / Group name: thegroup.name
• IPSec key / Shared secret: sharedkey
• Username / Account: user.name
• Password: Password of the user user.name

The input doesn't shows up on our machines:

• OS Name Microsoft Windows 11 Pro
• Version 10.0.22000 Build 22000

Is there a register key or anything to setup first?

Is there any VPN Client able to fit the requirement and that could be use by an entreprise ?

Does anybody already find a solution to this problem on Windows 11?

Answer 1

The only IPsec related Windows built-in VPN clients are:

• IPsec IKEv2
• L2TP/IPsec

Windows has no built-in IPsec IKEv1 Xauth (Cisco-style) VPN client.

Some people recommend the Shrew Soft VPN Client for Windows, in particular the Standard edition which can be used for either personal or commercial use:

see the following doc on how to configure the Shrew Soft VPN client for Mutual PSK + XAuth :
