Microsoft games using teredo, like Forza Horizon etc.?

User Info:

OS: Win10 x64
Program: Microsoft games using teredo, like Forza Horizon etc.

I often get google results to some of your sites, which is nice and helpful.
But now i got one conflicting result regarding a default setting, here
https://www.colorconsole.de/cmd/en/Windows_7/netsh/interface/teredo/set/state.htm
my Win10 x64 21H2 defaults teredo to "disabled" instead of "client" as in your "How-to"
maybe this could be very helpful to other visitors.

I had a problem where teredo could be triggered to ON by a game start or the NAT Teredo status test in windows settings xbox-tab.
But a game wich would not trigger again before the awaited refresh will lead to teredo turning off again while in a online-match.
And a symptom of that behavior is as example, that the windows-settings xbox NAT-Status check only shows a working teredo after a second try, but never on the first try after windows settings was completely closed.

after i used
netsh interface teredo set state client
instead of
netsh interface teredo set state default

the mentioned xbox status test worked on first try

without your site i would´ve never found that out

thank you
kind regards
