So, I just got my new PC and installed a popular FPS series: IW5 and IW5M. For some reason, I can't connect to any servers. I tried to open the ports on Windows Firewall and COMODO Firewall. I have a static internal IP and DMZ is enabled. System time is synchronized and router's time is synchronized. Is this a common problem after installing Windows?

Oh yea. I forgot say that COMODO Firewall is in Game Mode

Doesn't game mode mean only that it won't minimise your game when it wants to alert anything?

I mean, nothing port-related

 

Try turning it off

Nope. Still can't connect to any servers. Already check server's status @ s.mufff.in/status
