I wonder if you also need to add "alias same_port yes" to the config file. I checked the man pages and this option makes the outgoing udp packets stay on the same udp port??!?!Unfortunately it looks like Quake assigns an idividual port from 1025-1500 for each user. I found this in some old tech information docs, but I wanted to make sure before I entered 400 alias line? Has anyone else tired this? Or is there an eaiser way? >alias port udp 206.254.73.254:6112 6112 >alias port tcp 206.254.73.254:116 116 >alias port tcp 206.254.73.254:118 118 > Shouldn't these all be udp? and an IP address of the cleint machine behind the firewall??? So if you wanted to connect to a server at 131.230.82.2 and you're local mahine is 10.0.0.4 and the machines talk on port 116 and 188 you'd have alias port udp 10.0.0.4:6112 6112 alias port udp 10.0.0.4:6112 6112 alias port udp 10.0.0.4:6112 6112 Right??! WOw now I'm really confused!!!!! At 07:19 AM 10/23/97 -0700, Steve W.
