mDNS-repeater is a Multicast DNS repeater for Linux. This program re-broadcast 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 :
