I haven't worked with multicast much, but from my understanding you
may have to join the router to the multicast domain.

The packets are addressed to 225.0.0.41 and static routes for that prefix are defined in both rc.conf files (I only use 1 multicast address, so I don't see a reason to use a multicast routing daemon).  Obviously, I don't believe the static route is defined correctly.
