Hello all, I would need to be able to modify the source ip on input GRE paquets. This is because I'm trying to setup a pptp tunnel, via a router that doesn't NAT correctly the GRE. The client receives GRE, but replies with it's own local ip, then my server cannot receive the answers... If I could just change the source ip on those paquets, that would be perfect...
