I'm not sure I understand, certainly. What do the port numbers matter? When doing static or dynamic NAT, it's usually the IP addresses that people are bothered about. I suggest either: 1. Give us a specific example of what you want to happen, showing us the source & destination addresses & port numbers for machines A & B, so we can see exactly what you want to do, or 2. Show us what wouldn't work using a standard 1-1 NAT ruleset, or a standard "masquerade everything behind one IP" ruleset Regards, Antony. -- I want to build a machine that will be proud of me. - Danny Hillis, creator of The Connection Machine Please reply to the list; please don't CC me.
