If I have an ethernet cable splitter (one cable to the router and one to my Xbox 360) hooked up to my modem will I still be able to run xbox live normally and have an open NAT? Also will any computers wirelessly connected to the router work at the same speeds online? By the way I have tried all the "how to fix your NAT for xbox live" stuff and I always screw it up, so I'm trying a different solution and this is it. Thanks for your help!
