UPNP stands for Universal Plug and Play it is basically designed to allow certainly ports to be opened dymantically if the router thinks it's safe. When you say it's disabled do you mean on your console or on your router ??? What router do you have. It will do you no harm enabling it on the router and seeing the difference. Does MW3 still have you are in strict mode ??? If it does enabeling UPNP should open the necessary ports. The advantage for this it will allow matchmaking to choose from a large selection of players which should result in a better experience.
This is for anybody else reading this, on most modern routers you should not need to manually open ports to play MW3 on an open NAT. Some ISP's for what ever reason disable it by default. If you are not using a router and just connect straight to a modern then your console is connected direct to the internet which means all ports will be open. I would not recommend this for a PC for security risks but a console is a little difference.
If anybody wants help with checking/setting their routers modems up correct please or advice on optimising their connection let me know let me know, you will be very surprised the effect of using internal telephone cable in the house does to your connection, am now then happy to help.
