I just cant fix this stupid teredo problem....

Hello Jason,

Thank you for your response.

If you are still experiencing the same issue after going over the solutions provided on our articles, it may be a possibility that some settings on your network or firewall settings are blocking the Xbox app to connect online.

To check the Firewall settings, follow the steps provided here:
https://support.microsoft.com/en-ph/help/4028544/windows-10-turn-windows-defender-firewall-on-or-off

Also, we do suggest to open ports on the router or gatewayso provide the best connection to Xbox
LiveServers.



Open the following ports:

1. Port 88 (UDP)
   
2. Port 3074 (UDP and TCP)
   
3. Port 53 (UDP and TCP)
   
4. Port 80 (TCP)
   
5. Port 500 (UDP)
   
6. Port 3544 (UDP)
   
7. Port 4500 (UDP)
   
8. 
   

Check this support article on Network ports used by Xbox live.

Hope to hear back soon.

I just ran a test with dmz set on my laptop's ip, and all xbox-related and teredo/ipsec related ports were open. and when i put the dmz on the xbox one's ip, still gives me the stupid cant find an teredo ip adress.... this is just beyond frustrating.

Like i said, it doesnt work because i cant see the Teredo adapter. But i already fixed it, in my case i just changed everything that could have to do with teredo on my fritz!box and then used the built-in windows "problem solving" feature for the xbox
live connectivity. then it worked
