Can someone help me understand how the mDNS repeater plays into firewall rules?
I have two networks LAN and IoT. LAN can access IoT without restriction. IoT has a Block any to LAN and Block any to This Firewall. However mDNS repeater is still working as I can see the mDNS advertisements from devices that are on the IoT network.
How is this possible? I don't see any automatic rules. Sorry if this is a newbie question..

There are automatic rules but you may not see them in the UI. The pass rule is there for all selected interfaces.

Even when I dump all rules via command line there are no rules for port 5353 at all....
