NATting and masquerading takes place on layer 2 (IP).
Actually, NAT takes place at level 3 (IP). The levels are: 1. Physical (Cat5, Coax, Fiber, et. al.) 2. Link (Ethernet, ARP, etc.) 3. Address/Routing (IP) 4. Connection (TCP/UDP) 5. Session (Um, TLS, maybe?) 6. Presentation (Not really used at all) 7. Application (HTTP et. al.) 8. User (ID ten T errors) 9. Bureaucracy Okay, I made up 8 and 9. Oh, I might have gotten 6/7 swapped, but I don't think so. You probably don't want level 2 "routing". What are you trying to do that makes you think you need it? > AFAIK, this will never work.

Yeah, port forwarding is probably what you want. -- Boyd Stephen Smith Jr. ,= ,-_-. =. [EMAIL PROTECTED] ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.org/ \_/
