I need to enable multicast routing, specifically mDNS, to allow clients on my wireless VLAN to Airplay to AppleTV’s on my media VLAN. I know the Bonjour service uses multicast address 224.0.0.251 on udp port 5353 with a TTL of 1, essentially making it non-routable without some type of repeater. I know older versions of RouterOS could obtain a multicast package, but I’m not seeing an option for that in 6.11. Is there some way to achieve multicast routing on the current release?
I’m thinking a mangle rule to increase the TTL on the mDNS query would allow it to be routed, but I still need some way to actually forward the query and the response across subnets. Any help is appreciated!
