I have a requirement to find out how, if at all, the Cisco VPN Client can use an X.509 certificate to prove the validity of a VPN Concentrator. -Much like a web browser uses an SSL cert to prove that a given webserver is valid. Note that I do not need to do cert-based authentication. I see that I can install a cert on the Public Interface on the concentrator, but can someone tell me how, if at all this can play a role in how the client checks the validity of the concentrator its logging into?
I have this problem too.
