Warzone 2100 Forums

Dear community,

I tried for 3 months to host a game in WZ2100 v. 3.1.2 and failed, I have red and followed the instructions on the internet but I is still not working.


Thank u very much!

You didn't open port 2100.
Your 2nd screen, either turn ON UPnP, or enable port 2100 in port mapping.

You can also turn on your DMZ (Demilitarized zone) which worked for me when trying to host games as doing 2100 was not working correctly. Usually found on your security settings in your modem/router (192.168.1.1). I reccomend turning it off when you are not hosting warzone games though!

Thank you guys for the help, I tried that, but... here is my status -> (Attachment)

I can not host, just join a game... Strange, because both requires the "lobby-server" :-/

In your third screen you map 2100 to 9990 and 2100. You can't do that.
Are you on a LAN? If so, you are supposed to open the LAN port, not your external IP.

- Never recommended. This is asking for trouble.

I got finally massages like these: "UPnP detection progress... UPnP detected game configured correctly on xx.xx.xx.xx (ext. ip) error connecting to lobby server, make sure port 2100 can receive incoming connections"

Game configured correctly AND error connecting to lobby server???

I activated DMZ and UPnP for my ip, opened port 2100 and 9990, disabled firewall.

Did you host the game? The message might be a false positive.

If so, you can check by leaving the game up for awhile, and then see if anyone joins.
You can also join IRC on freenode #warzone2100-lobby and check if the game is shown there.
