pfBlocker blocking all TP-Link DNS?

I watched Tom’s videos to set up my SG-3100, part of which was pfBlocker. I am not monitoring daily, but it seems that today all DNS traffic from my TP-Link IoT devices are being blocked. I have a single Unifi AP, and the Unifi Controller is reporting DNS timeouts. I am not sure where to start; any help would be greatly appreciated.

Make sure the system is pointing at pfsense for the DNS

Have gone over pfSense docs. I think I’ve configured correctly.


Everything was working fine up to the day of my post. It seems I got it working now. I had a firewall rule that prevented access from IOT VLAN -> IOT VLAN; turned off this rule and instead opted to make wireless network Guest in Unifi Controller.
