Hello!
I want to create a DNS group, which automatically captures all Teamviewer server. I know how to create a DNS group. But which DNS name should I use?
Thanks in advance for your help.

This is a very dynamic problem...You can not use wildcard (*) with network definitions (e.g. *.teamviewer.com)
Now it depends on what your aim is?
If teamviewer updates & connections should work everywhere:
In Sophos Webfilter there should already be an exception for Teamviewer like
^https?://(?:[A-Za-z0-9-]+\.)+teamviewer\.com/?
Just check/add exception for authentication, URL Filter, SSL-Check, extension blocking and MIME-Typ blocking and teamviewer & updates should work now.

As already said this is not really possible/useful for the Firewall because you can't use */wildcard-definitions...
I know that there is already a feature request for that use case...
Teamviewer is very dynamic - you would need a list with ALL DNS-Server addresses from Teamviewer and add every single DNS-Host and I think there will be still some IPs of Teamviewer missing...
I prefer to use Webfilter/Proxy for Teamviewer traffic...
In your case it is maybe easier to open Teamviewer Port 5938 generally on Firewall than to add every Teamviewer DNS-Host...
