I followed the wiki article and have unbound now running and working (using port 15353 sice 5353 is in use).
sudo pihole -a localdnsport 15353
Does not work for me, it seems to not support the localdnsport option. Configuring from the web console is also not possible since it does not list the “local DNS server on custom port” options as seen in the screenshots.
pihole up shows the system as up to date. What am I doing wrong here?
