Using BIND for DNS queries ? (newbie)

  • FreedomBox is plugged into a router at home
  • Bought 07.2021
  • The version of FreedomBox is 21.4.4

So one thing I expected by using Freedombox was to bypass my ISP DNS lookups to avoid DNS mangling.
So I see there is BIND but what could I do with this? Is it even possible to achieve what I am looking for? How to make my connected devices on the network use FreedomBox DNS instead of my ISP provided ones?
I have read and followed the instructions on the manual. But, I’m quite lost tbh…

You would need to configure each client device’s network settings, and set the DNS server to the local IP of the FreedomBox.

Yes I did it but I can’t access internet anymore with this configuration.
On the BIND config page, I set Uncensored DNS servers (aka CensurifriDNS) as forwarders. May I have to leave it blank?
