FreeBSD and almost all network cards support Multicast by default. The only kernel changes that are required is when you want to run a Multicast router on the machine. most likely you have a firewall rule that is blocking multicast from being sent and recieved. if you do not have any firewall rules enabled, run tcpdump on the interface and then start a mulitcast program (sdr, vic, vat, rat). The multicast program will make an announcement to the network that it has joined the group that you should see on the tcpdump. --mark tinguely.
