I have a Cisco 3825 at work and I've set up the EasyVPN. I can connect to it from my Linux machine using Kvpnc, but I cannot connect from a Windows machine with the latest VPN Client (5.0.04.0300). Windows gives me the error 412. In the Linux connection I've setup the advanced settings and specified the DH group which Windows does not show. Anyway to get this working?
I have this problem too.
