Other software that may be useful is [https://manpages.debian.org/stable/igmpproxy igmpproxy] and [https://unfix.org/projects/ecmh/ ecmh] For testing and usage, smcroute can reflect the multicast to other attached networks. The ~~old~~smcroute ~~SMCroute~~2.4.4 as found in Debian 11, would not configure the interface without an IP address on it, however the very latest smcroute allows 0.0.0.0 to be used to originate the IGMP3 joins, this needed the upgrade from ip_mreq to ip_mreqn in the smcroute code. Additionally the sysctl rp_filter is disabled on $DEVICE and "all" to allow the incoming multicast without a matching outgoing route, also desirable. iptables and/or nftables would still be used to filter.
