So far I have nothing working.

I assume that the mcast traffic is not arriving at all IPs. <wild  
guess>Either because on overly restrictive jail check, and/or just  
because there's no code which is distributing the traffic to all  
IPs.</wild guess>

It seems kern_jail.c is a place to check if there's some code which  
handles this. Maybe prison_check_ip[46] if mcast is on top of this, or  
something new to write if mcast is a different "AF". Again, this is a  
wild guess, I don't have enough understanding of the network code in  
the kernel to even make educated guesses about the real reason.

Bye,
Alexander.
