If you are Experiencing issues with a Pi-hole install that has non-standard elements (e.g you are using nginx instead of lighttpd, or there is some other aspect of your install that is customised) - please use the Community Help category.
I did configure pihole unbound but I am not entirely sure if that counts as a non standard element.
I am configuring each device's DNS in order to be connected with the pihole
Expected Behaviour:
Raspberry pi provides adblocking to all clients that are set up with the piholes DNS.
Actual Behaviour:
It seems like pihole is only providing ad blocking on the raspberry pi itself.
