"Quote from: ZkDpsQ64FFoezpgr on March 11, 2026, 01:01:50 AMThe 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'd be more wary of the interface filtering than raw flood risk, mDNS gets noisy fast once multiple VLANs can see each other. The IPv6-only gap in UDPBroadcastRelay is exactly why this package looks tempting though.
