HI,

I discovered a similar issue where the dhcp range is empty in the dnsmaqs config I opened a tickert for this [1]
My observation is that in such cases where no ethernet cable is plugged into the router while it boots up, then there is not carrier detected and hence no dhcp range set up - no dhcp working. Once the carrier is detected it should trigger a hotplug event the start the dhcp with proper range on that interface, but this is not working currently.

Greetings Thomas
