I have installed Cisco VPN Client on a Windows 2000 Server and I would like to established a IPSec tunnel with a Cisco Router. The IKE Phase 1 is ok, but I then didn't get any prompt for the XAUTH autentication.
Without configuration or debugs we might not be able to help much... On the other hand, preliminary things to check are:
make sure that authorization commands are correctly configured (I assume that they are if you have other PCs connecting fine to the router)... also make sure that the client authentication commands are correctly configured...
Thanks for this feedback. All other vpn connection are working fine, the main issue I have is that the IKE Phase 1 is ok and the IKE Phase 2 should start as soon as the user is authenticated with xauth. But... Xauth prompt doesn't appear. Logs on the vpn client looks like:
We found the problem. When connected to the Windows 2000 Server through a terminal session, the Xauth popup doesn't come. If connected on the console of the server or through a connection like VNC, all works fine.
