Nat type open on xbox one but strict in cod ghost??? please help

Strict NAT

I cannot for the life of me figure out why my xbone is on a strict NAT. it wasnt yesterday, ive even set my xbox as my DMZ on my router still strict NAT. anyone else having this problem?

 

I don't know if they fixed it, but there was/is a bug in the dashboard that bugs and alters your NAT settings if you have your console set to Instant on. A lot of us, had to swap to Energy Saving mode to keep the dashboard from altering the state of the
NAT. It would literally change it from OPEN, to limited for no reason. Some kind of networking bug. The Energy Saving mode just clears the cache and resets it on booting. Perhaps try that. It worked for me, but this was an issue with the August dashboard
before they released it to public. No clue if they fixed it before releasing it to public or not.

 

No luck with that.. I was hopeful! Lol

 

Unfortunately this sounds like you are on an ip sharing network in your apartment building. The error messages you get sound like this. I'd suggest to ask your facility management on how you are connected to the Internet and then come back for further assistance.
