I have my VPN security gateway configured to only allow clients having a VPN computer certificate issued by a specific CA. Such a certificate is correctly installed on the client side. In addition to that, another machine certificate is installed on the same client and needed for other purposes.
Now, when the Windows L2TP client tries to establish a connection, it presents the other certificate to the Security Gateway. It does not use the certificate the Security gateway is looking for, which results in the VPN connection being rejected by the Security Gateway.
How can I force the L2TP client to use my VPN certificate issued from the correct CA and recognized by the Security Gateway instead of using certificates intended for other purposes?
Best regards, Tom
