I have a fresh install of Pi-Hole using DietPi. My 2 clients have the DNS hardcoded and Pi-hole is serving DNS and blocking ads. The issue is that the dashboard shows no queries/logs. I also do not see my clients. I have a DMZ subnet where the Pi-hole lives so its not in the same subnet, I have firewall rules allowed for communication.
I installed wireguard on the raspberry pi and when I am on the VPN, I can see the queries but I assume because that is all handled on the server locally.
