I'm using freebsd as a multicast router here, and I need to be able to
allow igmp requests from a network so viewers can join a group, but
block transmission of multicast packets in general.  ipfw only knows
about tcp and udp, and from looking at the code and include files, it
looks like the protocol specification interface is very limited.  You
need to be able to actually specify the protocol by number if the name
isn't known (e.g. rsvp is 42, I believe, and I'm sure there are others).
