Halo 'Lan Lobby' problem

[J@ffa]

Hi.

I'm running v1.03 of Halo on several Macs to play a LAN game, but when I start a game, it doesn't show up in the Lan Lobby of any of the other Macs, and vice versa. The game can be connected to by using the 'Direct IP' option, but that's a little annoying. Anyone know why the Lan Lobby might not be working? Thanks :)

Well how are they connected, and are they on the same subnet mask. If one computer is on airport, and another on ethernet is airport to ether net bridge turned on. If air port being hosted by acomputer,Have you set it's airport id manualy to match it's ethernet ip? Your using two diffrent legal copys right?
