No, it isn't set to broadcast in the lobby.
I've done some more troubleshooting: I connected both machines to
eachother via a crossover cable, bypassing any hub or "router".
I ran a packet sniffer on both machines, and I found that when searching
for LAN games, the client sends UDP requests for ports on
255.255.255.255.
When I specify an IP, the client sends same UDP requests (ports ~ 32200-
32300) to the IP of the server.
But none of the UDP packets show up on the server machine.
I am running Ethereal. I am pretty sure that even if a Windows
firewall, or ZoneAlarm was blocking something, the packets would at
least show up on the ethernet device, and show up in Ethereal, THEN get
blocked by the higher layer firewalls.
Any ideas? Maybe there is some network/security option in Windows that
I'm missing.
I appreciate the help, by the way.
