Stuck with Teredo IP address problem

Well, as I said above. If you did not have problems before and are on the same router and connection you need to do a factory reset on the One.

If you are on a new connection you should do the same first. If it still persists then, we need to drive deeper into your connection and router configuration.

It happened with the old router as well. I thought the old router was the problem because I had lived at college last year and didn't have any problems with the xbox.

Does this happen out of a sudden and was working before? Even with the new router? If so, the only solution is a factory reset of your Xbox.

If this is only happening since you exchanged the router and has never worked on the new router it should be a misconfigured router. Please check especially if port 3544 UDP may be blocked or if the Teredo tunneling may be blocked as protocol.

I have the same problem too. It says “ Cant get a Teredo IP address.” Ive tried everything already.

im getting this cannot get a teredo ip address and rang BT butthey

said its an xbox issue with the firewall.detailed nat information is saying your network is stuck behind a firewall or not connected tho im connected to the internet.really stuck here don't know what to do
