need help with teredo

We need the model of the router to help, teredo is a touchy topic and is really related to isp mostly, some isp support ipv6 but refuse to open port 3544 that teredo tunneling uses. Just post the model/maker of the router/gateway and we might be able to
help.

Hello, it seems like you need to enable Teredo Tunneling.

This article will help you with that:

How to install Teredo Tunneling Pseudo-Interface on Windows 10

Hi Ares,

Thanks for your post! If there is no teredo driver, try checking with your PC's or Motherboard's manufacturer. Additionally, be sure to check your router's configuration for teredo tunneling support, if it's not supported, it may need a firmware upgrade.

I hope this information helps, thanks again.

Hello EPICONLP,

Teredo is a networking protocol that’s used to establish secure communications between clients and servers, and to facilitate connectivity
between devices behind routers that use network address translation (NAT).

Sometimes, you just need to go into your router to activate teredo, or "Teredo tunneling". If it is already activated, turning that setting off and then back on can help.

Don't forget to try the troubleshooting in that support article given to you by Amber above. Click on that link, and select the teredo error to begin troubleshooting.

Hope this helps!

sign in to the GUI of your Fritzbox, there is an option to enable Teredo. This feature is disabled on the Fritzbox, by default, but need to be enabled for the Xbox to be able to establish a Teredo transition between Teredo peers, or peers that reside on
the native space of IPv6.
