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...

Thanks for your help,
