Very good. ;-)

Running here since ~12 hours. Absolutely no problems. Just for fun, I
even told Firefox to use DoH.
And: I told my client PC to use 1.2.3.4 as DNS-server. He had no chance.
DNS was still working as before.
Furthermore I can see the redirections from our blue clients (nasty
programmed apps).

Settings:
DNS-Server with nine DNSSEC-entries, status on 'dhcp.cgi' is "Working",
DNS-Protocol: TLS, QNAME-Minmisation: Strict. Running 'unbound 1.13.1'.

What about something like this?

Opinions?

Best,
Matthias

P.S.:
One (last?) thing to do would be to merge 'dnsntp' (init) and
'dnsntpctrl'.(c) into one C file to get rid of the still remaining
init-file. But sorry, that's for someone else, please...

The cases for the RETURN ( DNS requests direct to IPFire ) should be nearly 100%. DNS and NTP servrs are published by DHCP or should be configured in the static case.
