If I ping 192.168.101.2 from the 192.168.1.1 gateway everything works But if I ping from 192.168.1.x to 192.168.101.2 it doesn't setup the tunnel, nor does it use the tunnel when there. I have narrowed it down to the use of fastforwarding on 192.168.1.1. Without fastforwarding everything works, with fastforwarding it does not. Unfortunately I found out ICMP is not fastforwarded, so I didn't try a TCP or UDP test. I am running 7.0-RELEASE ( most recent, but it was broken before ). Is fastforwarding supposed to be compatible with gif tunnels, or is this a bug?
