Do not recommend enabling UPnP as it poses security risks – do it manually.

Hey!

I’ve opened all ports required for NAT type OPEN in games as MW2. My router tells me they are open, but portforward.com program says they’re closed. Anyways I had NAT type open right after I’d open the ports in my router. Three days later, out of nowhere, I was back on NAT type strict.

The game is not balanced for lean. Obviously.

You will have to specify IP address of your computer where you are running MW2.

You can find out your address by clicking Start | Run then type in cmd.exe and press enter.

Console window will pop up and then you type in ipconfig and press enter. There you will be able to see your IP address.

Brian,

Static IP would be advisable, but it is not required. Opening ports on Xbox? I never used an Xbox before, but if it has somekind of firewall then you’ll have to disable it or, yes, open ports on it. But I doubt that this could be the case.

I’ve seen many port lists that should be opened for MW2, but the configuration I specified does work for me on PC. I can’t guarantee that it will work on Xbox.

Thanks for the help, my NAT is stuck on Strict. Just to make sure I have everything straight before I mangle the settings on my router and xbox:
Using a Lynxis 54gv5 wireless router
1) Do I need to assign my xbox a static IP?
2) Do I have to open ports on both the xbox and the router?
3) I have seen a list of several different ports; how do I know when I have it correct (NAT open?)
I’m sure I’ll think of something I forgot and need to know, but this should get me started. Thank you again!
