Good day!
We need to connect an STB device over wi-fi to the router. STB uses multicast only. Using udpxy is not possible. Original firmware forwards multicast over wi-fi using mac changing technique. I.e. router changes destination mac address from multicast to unicast mac address of multicast group subscriber. On Asus routers this feature is called "Wireless Multicast Forwarding (WMF)". On Mikrotik it's called "Multicast-helper". So, the question is: Can I enable this on TP-link wr741nd with ОpenWrt? It works in original firmware. How is it implemented? Is it a feature of wi-fi chip driver or kernel patch or patch of igmpproxy or something else?
