I already tried to turn off my router, the game is on in Firewall.
I dont know what to do, Please, there is any good solution for that?
Solved! Go to Solution.
In order to get your NAT type from Strict to Open, you will need to establish a static IP address and port forward. If you have questions on how to port forward, please contact your ISP or the router manufacturer for additional support.
Here are the port numbers you will need Activision Support .
Interesting because for UDP to 'work' it needs to be opened first on the 'router' then router either blocks or opens UDP traffic to the PC. Again, DMZ Host is by far the easiest setting otherwise sure for BO2 open UDP ports 3074...3076 on the Router; 3075...3076 if there are multiple PC's/Consoles playing and your Router supports it.
However, Ghosts requires you to forward the following ports: 1116-1150,5165,27900-27901,28910.

me and my frends put UDP port 3074 and my NAT is open now and we dont have any problems with that
I cant find my router's settings in My computer like he does.
The DMZ Host is a Router setting, so to access you must first log into your Router; most home Routers have and IP Address of 192.168.1.1
If your router has firewall, disabled it. Some Routers are bad that may cause the ports to close.
If you have DMZ enable and still not able to get "Open" NAT, download a port scanner software to check what is using the same ports as your game.
Download it from CNet downloads. Search for port scanner.
If it is windows services or an application that is using the same ports, try to disabled them. If it is windows services, try to set them to manual instead of automatically during windows startup provide that it is not an important service which you can disable. If it is an important service, try to disable it temporary when you want to play your game.
All you have you to do get Open NAT is enable UPnP(Universal Plug And Play) setting in your router. After doing this, Cod Ghosts will dynamically tell your router which ports it needs to open, and will open them during gameplay to give you open NAT and will close them when you exit the game...in other words UPnP does the port forwarding for you, but it closes them when your not playing the game...which is better for security and playing the game.
Any router that is RFC 6970 Compliant properly supports UPnP standard and will work correctly....As far as i know, any router made by Cisco and(Linksys), Netgear, and ZyXEL, etc..name brand routers all properly support UPnP according to RFC 6970 and will work right, if you don't have an RFC 6970 compliant router, I would suggest getting one. They are not that expensive and will save you a ton of headaches.
All it required of me to get Open NAT was to check the UPnP box and restart my router and I have open NAT ever since, of course it doesn't help lag though...just saying.
