I have PC1 going to Router1 going to firewall going to Router2 going to PC2. This seems like a simple solution but i cannot get it to work.
All it has to do is accept any GRE traffic and drop everything else. It seems like its only pinging correctly when sent directly to the router or firewall but when I ping from pc to pc it ignores the rule completely.
