I want to configure ipfire to use secure DNS requests. Therefore I set up two DNS server addresses: 184.108.40.206 (digitalcourage.de) and 220.127.116.11 (dismail.de) Both support DNSSEC and DNS over TLS. How can I configure ipfire to use this standard? Currently I can see under status/connection that the DNS Server requests are sent to Port 53, not 853.
You’ll need to use the custom script here to get this setup and working. That thread also references the old IPfire forum where most of the DoT development updates were logged in the old forums thread.
