(adsbygoogle = window.adsbygoogle || []).push({}); I had a twitter request to help someone on their NAT so I figured this is a good chance to help others! Keep in mind you'll need to select the game(s) you want to open the ports for. This method works for both PS3 & Xbox 360! Below I've included a list of the MW3 ports




PS3 & Xbox Ports to forward:
TCP: 3074, 27014-27050

UDP: 3074, 27000-27030

Misc Tips:

Finding the IP of your router/modem on Windows:
1) Start --> Run --> CMD
2) In CMD command prompt type "ipconfig/all" (without quotes) and press enter
3) A bunch of mumbo jumbo comes up, but you're looking for the numbers next to Default Gateway. It should read something like this 192.168.1.1
4) open your internet browser and type in the default gateway IP

The absolute best solution to any of these problems is either run your ps3 wired or get home plugs and wire you ps3 to them and the router, you'll notice your connection is vastly improved. I could never go back to wireless for gaming.

Okay I need help when you mean
TCP 27014-2750 it is that the port opens at 27014 and closes at 2750

Yeah i think so

another networking guru might be able to confirm this, but I believe it to open 27014 through 27050. Meaning 27051 is "closed."

My wife natalie always opens up to me ;]

jibber jabber jibberooo. It's like Adam Sandler of randomness entered this thread.

If you have something constructive to add, please do. If you guys have serious questions, let me know.

I once saw a lemon

for the people who have problems with port forwarding or dmz mode:

Thanks for the input. I updated the first post with some misc tips. I may add to those moving forward. :y:
