Fix for Teredo error NAT unavailable.

Thank you for contact us! I'm Anderson, an Independent Consultant and a Microsoft user like you.

Good evening

Teredo is a protocol that enables Xbox consoles to communicate with other devices and services on the internet. NAT stands for Network Address Translation, and it is a technology used by routers to allow multiple devices to connect to the internet using a single IP address. If Teredo is not working correctly, it can cause NAT issues on your Xbox console.

these are the solutions that Microsoft guides

Hello JWingZ1,

Do we have any error message like this?

• Double NAT detected
  
• Can’t get a Teredo IP address
  
• NAT Type: Unavailable
  
• Teredo is unable to qualify
  
• UPnP not successful
  
• Error code: 0x89231906
  

Let me know.

Regards,

Ok thx for replying, I tried to use DMZ without upnp and I selected the last port and nothing changed then I turned upnp on and rebooted my router and now I have unavailable Nat type with teredo error even tho I have IPv4 and not ipv6 because I heard that
the tredo error has something to do with ipv6 anyway I restarted my xbox to see if something changes and it did, now my nat is still moderate but my port is 54145 and its usually 3074 and now I selected the last port as you said and now I got unavailable nat
type with teredo error then I clicked on automatic and the port is now 3074 and it's still unavailable and thnx

it says nat type unavailable also it says can't get a teredo ip address
