Im trying the latest PiHole on an RPi3 with Rasbian Lite. Complete new installation. Everything still on default. Everything looks okay. Web interface is up and running. But when I change my router, to pihole dns, nothing works. So I reversed the router configuration and tried to change the DNS of my Phone manually to use PiHole DNS. My phone immediatelly told me: no internet! Then I changed the DNS on my phone to google dns (8.8.8.8) and I had the same problem!! So also google DNS did not work. When I changed the DNS to my routers IP, everything worked!
So it seems my router is blocking all upstream DNS requests?????
I have Fritzbox 7581 and no special config. All pretty basic. I have been going through all settings but did not find anything strange....
Please follow the below template, it will help us to help you!
Expected Behaviour:
Changing DNS on my phone to PiHole or to Google (8.8.8.8) should work.
