So I have moderate NAT problem, and it's really driving me crazy. I have 2 consoles set up using the same router as follows:
1. Xbox 360 Elite
-> LAN switch->Home plug->Router = Open NAT (works like a charm)
2. Xbox 360S
Both consoles use the same router, are on the same network, have manual IP addresses (but different IP). For the 360S I have tried wired and wireless, restarted everything a bazillion times but I still have moderate NAT. I have managed to join parties and/or games of some friends but not of others.
My router has UPnP on, and everything that is necessary excluding port forwarding. The router should not be problem because the Elite works fine. So why isn't the other console working as it should?
