I started a game with my computer and one with my roommate's computer, I can see both games and try to connect to his through the console.
I tried the commands:
net_start
sv_lan 0
connect 192.168.1.101
The server info box says that my roommate's server is not responding. On his computer he can not see my game listed.
Also, before I used the command sv_lan 0 I was only able to see two internet games, the Warrior Nation servers. Now I can see many more. However, sv_lan 0 is supposed to make my server visible on the internet list, but it is not.
I'm sorry to keep bothering, but do you have any more ideas?
