Cant get a Teredo IP Address Issue (3/21/2015)

Dear Support ,

I have had an issue since I updated my Xbox ( March updates) and my NAT is under Strict mode . I went through all of the possible ways . I have done following things :

• Port Forwarding configuration on my router
• Assign Statistic IP address
• Clear the MAC addresses from Xbox one and reboot it
• Try to setup as an Energy saving on the Power and setting option
• Connect my XB1 to the Wired ( Direct connection)
• and every and each possible ways on Internet
• Disabled Security firewall on my router
• IP6 is disabled

but still I'm getting the Strict NAT . When I go to the Test Multiplayer Section it says : Your network is behind a firewall ( or not connected) .

I live in Atlanta , My modem is all in one : Motorola 6580 . ISP : Xfinity Comcast .

Please advise ,

Best Regards,

:)

Cant get a Teredo IP Address!

This indicates that at least one UK university has chosen to block all Teredo traffic:

I am having the exact same problem, I'm sure it was the march update as I have tried all the above steps as well. My Nat has always been open and now is strict with the same "your network is behind a firewall or not connected" error. Please update if you
find a solution to this.

 

Hello Tomber1,

This happened to me after I updated my Xbox one . I did not have any issue before that . If both of us find something we will update here .

Regards,

 

I managed to fix my problem with a factory reset, just thought I would update and let you know. Still not 100% sure what exactly caused this issue, but after trying every possible troubleshooting step with customer support I decided to try a factory reset
before sending my xbox for replacement, this has (so far) fixed the issue for me.

 

Thank you for updates . Do you have Viber or Skype if I call you to ask more questions ?
