Duke Nukem 3D using TCP/IP ?

OK, somebody over a Evil's place tipped me off to a patch I could download for DOom about a year ago that let me set up lan games using TCP/IP protocol. Forget what it was called but I got it off id's site. It really made getting a game of Doom running over my lan a breeze.

The question is, is there anything like that for Duke Nukem 3D? I'd love to get that set up on my lan but I'm not really a network wiz and I've never had any luck getting that older protocol to work. I can't even remember what it's called!
