[edit] Network settings

Port 3074 (UDP) must be open to join and host multi-player games. Unlike Black Ops, the game does not support automatic port assignment through UPnP.

Users may opt to host their own dedicated, unranked multi-player servers as an alternative to the ranked matchmaking. This requires the hosting computer to have a sufficient processor and a minimum bandwidth, and the game to be installed. The server is launched from iw5mp_server.exe and can be configured with the play list recipes and server.cfg in the admin folder. In order to join dedicated servers, the option must be enabled from the in-game menu under the Dedicated Server category. You may list game servers using Steam's Server list function, and view the status of any server through the Join Game dialogue, or use the in-game server browser found under the Servers menu.
