Teredo problem on windows 11

gleiches Problem, nichts hat geholfen... dann fand ich die Lösung:

Teredo don´t work, now i found the Answer:

1. Windows Keys + R

2. gpedit.msc

3. Under Computer Configuration > Administrative Templates > All Settings

4. Find "Set Teredo Client Port" , "Set Teredo Default Qualified" , "Set Teredo Refresh Rate", "Set Teredo Server Name", "Set Teredo State".

5. Now, what you do is double click it, choose "Enabled" and change it to what I write below, some of these are not necessary but just change all of them :).

Set Teredo Client Port - Enable - input " 0"

Set Teredo Default Qualified - Enable - choose "Enabled State"

Set Teredo Refresh State - Enable - Choose "30" or "20"

Set Teredo Server Name - Enable - input "win10.ipv6.microsoft.com"

Set Teredo State - Enable - choose "Client" (If after doing all steps it fails, try choose Enterprise Client instead.)
