Hello, Iam trying to build the system, capable of making NAT for pptp connections Debian 3, Kernel 2.4.22(with debian patches) patch-o-matic 20030912 I found that if I apply PPTP patch to my kernel and compile it with GRE protocol support and PPTP protocol support the simple command iptables -t nat -A POSTROUTING -o eih0 -j SNAT --to-source $myIP failed to execute with the following: iptables: Invalid argument May be it's a bug in a patch-o-matic PPTP patch? Is there anybody, who succeeded building the system capable of masquariding more than one PPTP connection to one server outside your lan?
