Description

Current packages like Avahi and PIMD can help users cast across VLANs, which is great for HOME/GUEST to IOT type scenarios, but it doesn't seem to address everything and IGMP proxies, snooping, etc. don't either. Google Home, for example, won't list speaker groups which involve the devices on the downstream VLAN. Apparently Chromecasts do some interesting things like changing source/destinations as Chromecast requires broadcasts to originate from an address on its subnet.

I found this package that runs a UDP relay daemon. [[https://github.com/marjohn56/udpbroadcastrelay]]

It's an updated version of a UDP relay from a few years back and it is working perfectly in identifying my Chromecast speaker groups on my IOT VLAN (while I remain on GUEST). It appears to be effective at all of these things:
  • mDNS / Multicast DNS (Chromecast Discovery + Bonjour + More)
  • SSDP (Roku Discovery, DLNA Media, Sonos, UPnP + More)
  • ifx Bulb Discovery
  • Broadlink IR Emitter Discovery
  • Warcraft 3 Server Discovery
  • Windows Network Neighborhood Discovery
  • Syncthing Discovery
  • Raknet Discovery (Minecraft)

This would be a great addition as a package in pfSense. As it stands, it is a bit tricky to run as a daemon (it hangs other services if not handled properly) and it would be nice to have an indicator on the dashboard with the other services when it is started and stopped.
