Add a route to the multicast group on the device upon which PPPoE runs, aimed at the openreach modem
echo ip route add 234.81.130.4 dev $DEVICE
=== Relaying the stream ===
It may happen that the computer hosting PPPoE is in an inconvenient location for watching and that other networked devices should receive copies of the stream. For real use an IGMP proxy would be used but for first testing [http://troglobit.github.io/smcroute smcroute] lets one try multicast even where clients don't send IGMP join and leave correctly, but this also means the stream has to be manually started and stopped.
For testing, using smcroute we can reflect the multicast to other attached networks. SMCroute does not configure the interface without a legacy IP, so can copy WAN address:
smcroute -l $DEVICE 234.81.130.4
now ffmpeg, vlc or other client can be ran elsewhere on the internal network, if their ethernet interfaces do not have legacy ip addresses and the client does not specify an interface for IGMP, use
