Just close your ports.
Hey guys,
Just a request if there is or if someone can make a tool which secures that you will never be the host.
Because being host in mw3 just SUCKS donkeyballs. The lag compensation just screws it up for the host.
Hope someone is able to make this, because it can help me out alot, because im host alot!

Just close your ports.
Disable UnPnP. That'll close the ports if they are port forwarded automatically. If you've portforwarded manually just delete the services you added.
You can also block the ports via some routers.
Convery's solution will work too, if you play on PC.
