Hi Ivo,
thanks for information. I suspect there might be problem with particular
domain and configuration combination.
Unfortunatelly it is hard to give any advice if we do not have exact
steps to reproduce including real domain name because we cannot see
what's visible in real DNS. Please provide real domain names so we can
have a look.

Hi,
I have also added logging:
policy.add(policy.suffix(
policy.QTRACE,{
todname('sub1.company.cz <http://sub1.company.cz>'),
todname('sub2.company.cz <http://sub2.company.cz>')
}
))
and I include relevant part of /var/log/syslog
... just names are not real company.cz <http://company.cz> etc.
and our domain has not (yet) DS record.
To me it seems that kresd finds real record for company.cz
<http://company.cz>
and then does NOT honor my policy for it's subdomains.

Hi Ivo,
what are symptoms? Does the query time out? Do you see anything in
verbose log? (Use journalctl.)
It is not clear what problem you see so it is hard to give any advice.

Hi,
I am not able to force knot-resolver to forward some queries.
I have real DNS zone and in internal network I have few 3rd level
subzones.
For them I would like to make my kresd forward
queries to our internal
DNS server (bind9).
My computer is not inside company nework - connected via openvpn.
System is ubuntu 18.04.1 (up-to-date) and knot-resolver 3.0.0.
Relevant part of kresd.conf is:
policy.add(policy.suffix(
policy.FORWARD('10.0.0.1'),{
todname('sub1.company.cz <http://sub1.company.cz>
<http://sub1.company.cz>'),
todname('sub2.company.cz

<http://sub2.company.cz>')
}

<http://machine.sub1.company.cz> @10.0.0.1 <http://10.0.0.1>
<http://10.0.0.1> DOES work
I have set verbose(true) but with no help.
kresd queries 10.0.0.1 for 'company.cz <http://company.cz>
<http://company.cz>' only, but
that's all.
I am just working on it on my ubuntu workstation,
but real target will be turris omnia with its kresd,
which connects via openvpn to company network.
