My BEFVP41 vp1 tries to connect to another BEFVP41 v2 which is behind a Netopia 3357W. I used static NAT on the 3357W pointing to the MAC address of the BEFVP41 v2. I can VPN only once; only after a warm restart from the 3357W. Afterwards I can't reconnect any more. Pinging machines behind the BEFVP41 vp2 is impossible- any suggestions ?
