Hi,
I use the link below to config my main xbox to have open nat to xbox live services. It works perfectly. Perhaps I bought a second unit and it still has strict nat. If i try to add on inbound same ports it said something about overlapping services. Im not sure if this is the correct way to go, any advice well be of great help.
Thanks…
