I have the CGNM-2250 and my xbox 360 wont connect to live. It comes up with a " nat moderate " error. My xbox is connected directly to the modem via an ethernet cable. When I test the live connection, it says that my "current network may limit my ability to join a multiplayer game". When I try to renew my live subscription, it comes up with an error code (80072741) and when I go to microsofts website, it tells me that my nat settings need to be changed. I've read some different solutions, I have tried unplugging and resetting modem and xbox. And I don't think I should have to buy a router for something that I was told would do that job. Is there any way I can change the "nat" setting? Or do I have to go out and buy another router? Any assistance is appreciated. Thank you.
