If you play a lot of online multiplayer games like Call of Duty: Black Ops or Modern Warfare on your PS3 or Xbox 360 you might have come across terms like Strict NAT, Open NAT, NAT Type 2 etc. If you are on NAT Type 3 then you will have some issues connecting to online games. This guide explains what is NAT Type and also how to achieve NAT Type 2 on your router.

What is NAT Type?
NAT stands for Network Address Translation. Well as a gamer you don’t need to go deep into the networking trivia and I’ll just tell you what different NAT Types mean.
- NAT Type 1 – Connected directly to the internet (no router/firewall). Should have no issues.
- NAT Type 2 – Connected through a router properly. Should have no issues.
- NAT Type 3 – Connected through a router without open ports or DMZ setup for PS3. Everything should function properly, but you may have connection, voice chat or other issues.
So, you might have already figured that it is NAT Type 1 or NAT Type 2 that you want for your home’s network in order for all games to work properly.
Basically, I was unable to find or join any game lobbies when playing Call of Duty: Black Ops on my PS3. When I checked my NAT Type I realized what’s wrong and then followed these instructions to get a NAT Type 2.
How to Change NAT Type 3 to NAT Type 2:
If you are directly connected to the Internet you probably don’t need to worry about this, but if you are using a router you need to modify a few settings. We have been using a Belkin N router so I’m giving instructions for this router. You should look for similar terms when configuring a router of different make and model.
Let’s first configure the router using our computer’s browser. Launch Router configuration page by pointing your browser to http://router or http://192.168.2.1
Select DMZ under Firewall in the navigation pane on the left. You might be asked for router’s password before the next step. If you have default settings, just leave it blank and click on submit to proceed.
Now, enter your console’s IP address and select the checkbox under Enable. You should set your PS3 or Xbox 360 to use a static IP address so that you don’t have to configure this again. If you are not using a static IP address then it might change upon rebooting your PS3 or router.
Click on Apply Changes and restart your console.
Now when you run an Internet Connection Test on your console( navigate to XMB > Settings > Network Settings > Internet Connection test for PS3) you should be able to see NAT Type 2.
There, you now have Nat Type 2. When you launch your game now you should be able to see your NAT as Open or Moderate now unlike the previous Strict setting.
Let us know how these instructions worked for you.
