I have been trying to get an L2TP over IPSec VPN using pre-shared keys working, but it just keeps failing with the same errors. For some reason it claims that it can't find a valid tunnel group. I am trying to connect using Windows XP VPN. The client is behind a nat, but I have already applied the NAT-T registry fix, but it didn't help.
