I tried IP-masq on a 1.2.13 kernel and it worked fine; some ip services
(ping, chat, possibly ftp (don't recall) ) did not work 100% in that
version. I understand that the 2.0.x kernels support more robust IP masq
capability.
You could also run proxy services on a firewall/gateway system.
Finally, I've seen write-ups where the "gateway" system used a reserved
ip address for the internal ethernet and connected to the Internet using
a shell dialup running slirp on the Internet-connected host.
