I've installed the latest client on a Vista Business Edition computer. The install and connection work fine. I am able to make a connection from the computer to the network behind the VPN but not the other way around. I confirmed this with a ping test. The user's login settings work fine on an XP machine so I don't think it's a configuration issue on the VPN server (ASA5520). Is this because the VPN client is not ready for prime-time on Vista?
