Thread: Port forwarding does not work.

Hi, I've bought new Modern Warfare III and would like to gamble again for a long time. Unfortunately, I have the problem that my NAT type is strict. I've spent hours looking at Google.de and found many results. Among other things, I have Upnp enabled, etc. But nothing helped me. And here are the ports that I want to share MW3:
PC:
TCP: 27014-27050, 3074 and UDP: 27000-27014, 27015-27030, 3074.

Did you down then on Local network device or game application add is selected? Otherwise, while you create the port-mapping configuration, but the router does not know what IP it should apply.

I would check especially if it is actually on the router or if the port will not be blocked by your computer.
