I've got a RVS4000 in Nevada and a WRV54G in Utah and I am unable to establish the tunnel. Has anyone had any success? DDNS is working properly, I ping the two routers from the router at the other end, but can't establish the tunnel. It seems like it is a problem with the key life time in the two phases. Anyone succesful out there in connecting a RVS 4000 to a WRV54g?
