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
Update
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.
