Opening firewall ports for hosting COOP Missions

[Nikoladis 12]

Which ports should I forward in my hardware firewall?

And is it just me, or should there not be a sticky post with this info, must be like the first thing all people going in here for the first time would like to know. :)

All UDP: game port, game port + 1, game port + 3

By default, the game port for the first server on an IP is 2302. If that port is in use, the server will increase the port by 12 and keep trying. (So 2314, 2326, 2338, etc.) The port can be changed on a per-server basis, but these are the defaults.

So with 2302: UDP 2302, UDP 2303, UDP 2305.
