I am requesting that the ability to specify the listening interface for the dns service so a firewall rule doesn't have to be written every time an ip is added to the router. I shouldn't have to drop packets because the dns service is listening on all ports. This way theres less overhead as no packets have to be dropped its simply not listening.

+2 it will be very usefull

+1 .
