I tried hosting a game on one xbox and then connecting to it from another that are both on the same network. When I do this I get the error message "The party may have an incompatible network setup. You have an OPEN NAT, which is the most flexible. Visit www.bungie.net/router for more information". I was reading the forums that go over this specifically this one. It says if you have UPnP flexibilities on your router you don't need to do anything with opening ports of the dmz. Yet I still can't get it to work when UPnP is turned on.

From my experience multiple Xboxes on one connection (router) can have unpredictable results.... Some routers handle it well and others don't. Also it seems like sometimes one router will work, and other times it won't.

So is there anything else I can try to do?
