i'm trying to set up a a GRE tunnel through a firewall but hitting some difficulties
i'm using loopback addresses at both ends and then an ip address per interface
i have routing between the two loopbacks and a trace from either to the other is hitting the firewall
i haven't put in any routes for the 2 physical addresses as they are both on the same 30 bit network and should see each other if the loopbacks can
is this right?
if not what else do i need to do and how can i check it out
i'm a bit curious as to how the two physical addresses are supposed to see each other
thanks to anyone taking the time to reply
