Installed pihole mostly following linustechtip forum's guide. Have not attempted DNS Over HTTPS or Unbound, whichever may be better. Have placed DNS 1 with pihole's IP (DHCP Resevervation) and DNS 2 with 184.108.40.206. Putting DNS1 and 2 as the same does not allow access to Internet, neither does putting in a dummy DNS for DNS2.
-OS: Raspbian GNU/Linux 10 (buster)
-Hardware: Raspberry Pi Zero W Rev 1.1 (Pihole connected via wlan0)
-Router: Myrepublic WiFi Halo (Fast 5366) Sagemcom
