Hi Otto,

I have to apologize. After trying your proposal it is working as expected.

Thank you for your help and sorry for the noise.

Kind regards

Felix

I want to use DHCP to get an IP address and the gateway address. But I want
to use my explicit defined nameserver (not the one given by DHCP).

Is that possible?
Why don't you try what I told you? It does exactly what you are
asking. You can also read about in in man dhclient.conf.

If you do not want to use dhcp at all you can use

supersede domain-name-servers 127.0.0.1;

(instead of prepend) in dhclient.conf

Hi,

status is showing:

      vatrox$ unwindctl status
      captive portal is unchecked

      selected             type status
             *              DoT validating
                       recursor validating

When I check with https://bash.ws/dnsleak, which DNS are contacted then
I can see, that not only the configured DNS is called. There are several
DNS as given by DHCP called, too. They, of course are supporting DoT as
well.

Kind regards

Hi,

I have a running unwind configuration:

/etc/unwind.conf

       forwarder 46.182.19.48 port 853 authentication name
dns2.digitalcourage.de DoT

       preference { DoT recursor }


Unfortunately this DNS from Digitalcourage is sometimes slow and
so the DNS
learned from DHCP (which is supporting DoT, too) is called.

Is it possible to prevent this fallback so that only calls to
the specified
DNS are made?

Kind regards

Felix

What does unwindctl status show?
