Kali.net alternatives

I used Kali a lot when I played Diablo 1. The game lacked an option to play online outside of Battle.net (which lagged as hell on my 56k), so Kali was perfect to simulate a lan over the internet, with much lower pings, since me and my buddies were directly connected.

Do you guys know of other programs/ways to play ipx games over tcp/ip? (freeware if possible)
