Nothing really special needed. You'll need the router to have a static
route for the .40 network via your internal gateway. Also, watch the
send_redirects option. If you're not careful your gateway will send
ICMP redirects to get the clients to bypass itself :)

You know it's working when tcpdump shows every packet twice but with
different ethernet headers...
