Ok, I have all the details, so I'll show exactly what my problem is. We have two xbox's soon to be three and it signs in one okay, but signs the other in with a restricted NAT. I know this is a frequent problem but can't seem to solve it.. Or recommend a router that will work. Here is the details:
-Cisco EPC2425 UPC router
-So its a cable router not going through DSL.
-It's connected to the xbox's through wired.
-Going through a hub router (tried without that but made no difference).
I have been advised to:
-Tick the UPnP box (to enable multiple xbox IP's.) And to make sure I'm not forwarding any ports and that I don't have an xbox as DMZ host. - Didn't work.
-Untick UPnP and forward ports for one of the Xbox's IP. And make the other Xbox's IP as DMZ host - Didn't work.
-Also tried port triggering and no luck.
Is there anything else I should try? Or is there something in options I shouldn't have? Please take a look:
(obv not enabled because was trying just UPnP)
Thanks for any help.
