Cool, cheers for that. I have no idea how to do anything wit iptables but i will look into it.
It’s possible it could also be your wireless router, if your sb and server are separated by wireless. Check the admin page of your router and see if it has any options for IGMP or Multicast (or multicast filtering) and try fiddling with the settings.
A firmware update might be a win, too.
