Thank you for your help, that sounded very good. Unfortunately, something is not working quite right.
If I enter 126.96.36.199 in the browser, I open a google page. On this one can manually make a DNS request.
I type 192.168.178.62 into the browser. I get a side of my pi-hole
So I give it as a static route
now I expect that with 188.8.131.52 I will get the surface of my pi-hole.
Unfortunately, when you enter 184.108.40.206, nothing happens anymore.
Am I still doing something wrong or incomplete?
Thanks for your support
