mDNS-repeater is a Multicast DNS repeater for Linux. This program re-broadcasts mDNS packets from one interface to other interfaces
mdns-repeater only requires the interface names and it will do the rest.
the ipfire standard installation defines blue0 for the wireless
interface and green0 as the internal LAN interface :
mdns-repeater green0 blue0
By specifying the -f flag for debugging, packets are printed as they are received.
