    SubjectRe: multicast Bug in kernel many versions...
    Date
    	Is there a reason you don't turn this on on your ethernet
    interface on the router:?

    ip pim dense-mode

    Or sparse-mode, depending on what you want to do? That makes
    it so that your ethernet will get multicast packets, and machines that
    do a /sbin/route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
    will see the traffic.

    That's our configuration here. If you have a access-list (firewall)
    configured on the router, add this to your permit section also:

    access-list XX permit udp any 224.0.0.0 15.255.255.255
