Don’t monitor Pi-holes and wireless APs?
Hi, I understand the documentation recommends disabling monitoring for Pi-hole devices and wireless APs / extenders in Simple mode. Can you further explain the rationale?
I currently have monitoring for such devices turned on, but I’m not seeing any network flow in FW app (which can’t be right). Is this normal behavior?
This is because by monitoring pi-hole and pihole is inside of your network, it creates a DNS lookup loop. This is purely because firewalla intercepts DNS.
1. Firewalla gets DNS request
2. Firewalla forward to pi hole
3. pi hole does a DNS lookup
4. Firewalla get pihold DNS request
5. Firewalla forward to pi hole
Another way to avoid this is to install pihole inside Firewalla, or turn off Firewalla DNS cache.
