Anything? How is rebind protection on my router going to be applicable to the issue I'm seeing?
On another note...
Looking through this thread, I see mention of editing:
/etc/dnsmasq.d/99-domains.conf
Is this do-able from within the Pi-hole web GUI? In my case, Pi-hole is running in a Docker container (from Pi-hole), and as best I can tell I don't have access to edit any files within its locked container. The only apparent access is through the application UI.
