I'm trying to setup linux as a router instead of NAT over a VPN. Here are the details: I have an FC3 machine running pptpclient. I have pptp configured to do "LAN to LAN" I have the FC3 machine set to act as a router: /proc/sys/net/ipv4/ip_forward is set to 1 After I make the connection I do iptables -F so it's wide open When I try to use the connection the machine is still doing NAT. Is there a way to make this box act like a router over the VPN and NOT do NAT? Thanks, James
