MW4 doesnt work with Network Routers?

Ouch, i can find the games, yes, but I cannot enter any MW4 game. Anyone know of anything to help me out?

When I hooked up to a new ISP with a Netopia Router I had the same problem and it was caused by not having needed ports open. Here's the URL for the MS Doc on what needs to be open for Directx 8 - MW4.

The easiest way to avoid problems is to run the DMZ option on your gaming machine. Install a software firewall ...you should have one already anyway and away you go no more ports to worry about. Not only will you have ports for MW4 to open but a lot of games use all different ports as well as webcams, VOIP ect ect.

Well I tried my webcam, voice chat servers, everything ran fine considering any internet type thing. When it came to connecting to MW4 or JK2, I found the games, but could not join them. Thanks tangy, i'll check that out. By the way, I have a LinkSys Cable/Dsl Wireless Router, and have practically done all of the work needed. Maybe its just the ports, I'll check that out.

Linksys routers have a DMZ option.
That is the easiest to use.
Just read the book on setting up DMZ,
cuase you have to manually assign your computer an IP in your network properties,
before DMZ mode will work.

The IP would have to be a local IP:
192.168.1.# and the final number has to be between 1-50.

Again, refer to your linksys manual, it covers all the details.

Of course, I wouldn't leave your computer on DMZ mode all the time, but to switch over to play MW4, and switch back to protected after playing is very easy thru linksys's web interface control.

Actually, my mistake, as soon as I got home I realized that I have a Netgear Cable/DSL Wireless Router. Does DMZ apply to it as well?

If it doesnt show up you may have to update the firmware. I just ran through that situation with a friend of mine. Lol he was able to open up 1 port so I could remotely setup his whole network.

You either have an access list running on your router or you're running a personal firewall on the PC. Make sure you have ports TCP 27999, 28805, 28806, 28807, 28808 and UDP 28808 open. If that doesn't work, make your router forward traffic from those ports to your PC's IP address.

Hope this helps
