DNS over tcp I have known and dealt with for a long time. No problem
there. Just mDNS over tcp. But you can see it for the same reasoning.
So that is probably a bug in the firewalld mDNS service rule.

He has been a great help on my mailserver work in the past. As far as
dutch, Amsterdam is my 'port' of call when I have an EU conference. I
have friends in Amstelveen that I stay with over the weekend. Love my
walk along an eco-canal to the Amstel river and the Rembrandt statue.
