Im just trying to setup a server within tf2. Not using dedicated server but just the ingame "create server". Now i was just wondering what ports i need to open so the server can function online as opposed to just over lan. Ive read something about have to use the console command sv_lan=0 but it was fairly breif about the effect of the comand. Or do i have to use dedicated server. If so am i able to play tf2 and have dedicated server running at the same time?
