Anyone installed mdns-bridge for IPv6 mDNS?

[ZkDpsQ64FFoezpgr]

The mdns-bridge package seems to be a feature-complete and up-to-date implementation of mDNS forwarding across interfaces for both IPv4 and IPv6. It handles only mDNS as opposed to the general-purpose (and IPv4-only) UDPBroadcastRelay, but at least it should make it easy for mDNS. It's getting harder to live without IPv6 nowadays, due to IoT gadgets, Apple and Google insisting on it.

There's no OPNsense plug-in for it, but it is in FreeBSD ports, so it should be ok to try. Anyone have any experience with it on OPNsense 25.7 or 26? Just looking for any concerns before I end up flooding everything :-)

I haven't tried it, but it would be great to have a GUI for it in OPNsense as one of the missing pieces for an IPv6 setup.  It looks like this one adds filtering based on mDNS labels.

One of the neat tricks of mdns-repeater which is sadly missing here is source-based filtering so that you could for example easily split an IoT interface into a couple of /25s and have the plugin itself block one of the two IoT ranges from discovery into the other VLANs.  It's not a perfect solution, but in IPv6 world it would save a prefix ID that would otherwise be needed for a second IoT VLAN.

But then again, keeping track of dynamic prefixes would be a problem for it... :(

EDIT: on second thought, maybe this one is even better as it can block reflection for all but specified hosts/services by label.  I think I misjudged it.
