I have 2 instances of pihole running in my LAN, I have wireguard on my firewall to get to those two ad blockers when I am away from home. I am so glad I was able to figure out how to get it back up and running without needing to redo all the work.

I have pihole do a lot more than just block ads; they also block a few different tlds (like .zip), they have different lists for different vLANs, and there are several different regex things I have in it.

They are not on the same pi, sure they are both docker images but they are on different pi’s
