I enabled the responsive firewall yesterday because we were being attacked. Almost everything seems to be working fine but today I got reports that computers that get their DHCP from the pbx are not working properly. DHCP gives the internal IP address of the pbx for DNS but it seems that the responsive firewall blocks the DNS port (53 UDP) even though the local network is set to trusted. I have to add a rule by hand to allow incoming connections to port 53. Why is this happening?

Is there another rule in Networks that rezones the local subnet(s) to Local or some other zone?
