Minecraft port does not work in windows 10?

Moin I never had problems with win 7 as far as that is concerned, but I have now released port 25565 as tcp / udp in my fritbox (ipv6 because dslite) My Windows 10 firewall should, if nothing is wrong with me, still you can't use the Internet Ipv6 on because server connect did I miss something?

And to the Pfrofis who say it's up to ipv6, it doesn't have it over a long time with ipv on win 7

I know that it works with ipv6, it works for me too… You can still save UDP, because Minecraft doesn't listen to UDP…

but you are already using the correct IPv6? So not the ones from the router…

and firewall with IPv6 please leave on…

and in the Fritz Box the firewall must also be correct… (route port 25565 TCP to the correct Ipv6)
