PiHole, not sure if they are working.

OK. I thought my PiHole setup was working fine. I am seeing queries logged in the PiHoles. Some requests state that they are being blocked. But I am now wondering if it is actually working.
When I power down my PiHoles, and do a ipconfig /flushdns AND clear my browser cache, pages are still being resolved. Yes I have two PiHole's running, but this happens when BOTH are powered down.

Why?

As you can tell, I am a noob at this!

Here is how I have it set up:

ASUS AX88U.

This is my PiHole DNS config page:

DOH!

I think I can answer my own question. I didn't reboot the router. It must have been using it's cache. After I did, no pages resolved.

My bad. Sorry.
