I have the same router as you Gerry (or close enough to it). Try this...

Port Forwarding Call of Duty - Modern Warfare 2 on the Netgear DG834PN

If you're playing on PS3, you'll need to open these ports as well...

Port Forwarding PS3 Call of Duty - Modern Warfare 2 on the Netgear DG834PN

And for X360, open these ports, as well as the first set of ports...

Port Forwarding XBOX360 Call of Duty - Modern Warfare 2 on the Netgear DG834PN

The instructions are fairly easy to follow, so I hope it helps.

If this isn't working for you, I believe the only other option you have, is to put your gaming IP address into the DMZ (Demilitarised Zone). By doing that, you are putting your system in front of your firewall, so there's no security. If you're playing on either console, it's not such a big deal, and it's the quickest way to open all ports and improve the network connection to your system.

If you play on PC, I wouldn't use the DMZ.

If you're having trouble, I'll try to help further...

first of all,thanks for the help!!!
i need to change my nat type cuz' i can't play spec ops with my friends-also sometimes during host migration i get kicked due to that!!

i run the game on pc

can u tell where can i find the ports of special ops and multiplayer in order to postforward them??

Icetyger · 02-19-2010, 11:26 AM

I would think the ports I posted above, will work for all MW2 online modes, including Spec Ops. Give it a try and see what happens...

gerry13cs · 02-19-2010, 12:18 PM

i finally made it
my NAT type in both multiplayer and special ops is now open-this change also made my game performance better!!
thanks a lot!!

Icetyger · 02-19-2010, 06:45 PM

You're very welcome. Now get in there soldier and take 'em down!!

Try updating your Router's firmware, my Netgear was having similar problems but a firmware update solved it.

where exactly is that jumper-when i open up my router i see blue category with services,settings,options etc ,a white box in the middle which has infomation about my ip adress and a second blue bocx on the right which shows some information about the router

First of all don't open your Router, that's not going to help.

To upgrade your firmware go here and download the file, then go into your router's control panel, there'll be a tab sayignn something like "Router Upgrade", click on that then locate the file you just downloaded.

i upgraded my router,deleted and reset the port about mw2.now my nat is open again.logically,it won't change again right??

**Dante** · 03-23-2010, 12:16 PM

Mine still fluctuates very occasionally but a restart of MW2 or Steam normally sorts it out.

Glad I could help.
