Ok Boys and Girls i think i found a solution to this problem...
First of all - I don't think the teredo adapter has to be in your Network-Adapter List with Window 10 - 1803!Maybe they got rid of it with 1803 as a visable adapter... i don't know...
Even tho my Serverstatus says "blocked" it still works now:
Here's my solution:
The Server you connect to, in my case "win1711.ipv6.microsoft.com.", should be the same as the one you're tryin to connect to (host)
To be sure that this is the case open up the Powershell as an Administrator.
Rightclick on the Windows Icon on the bottom left corner of your desktop and open "Windows Powershell (Administrator)"
Then you're gonna type in the following commands and press enter after every line i write:
netsh
int teredo
set state servername=win1711.ipv6.microsoft.com.
You can use the command "show state" to see your current teredo adapter settings while in**"netsh int teredo"** as seen above
Oh... and one more thing:
Be sure to activate the Windows Firewall!
You have to have it activated.
You can set this in the powershell aswell - heres the command to do so:
Netsh Advfirewall set Currentprofile Firewallpolicy Blockinboundalways allowoutbound
If some of these settings are not like this, you can look up how to set every setting on your own on the internet!
- Dr. Google knows everything!
I hope this could help you with your problem!
Kind regards,
Juri
