A better approach would be to find the multicast device that someone has
connected to your network and put it to bed. You might also want to check
your bastion router filter lists as nobody should be routing packets to or
from multicast addresses over WAN links unless they're specifically part of
Another possibility is that you're the target of a DoS using spoofed
addresses, or a misconfigured MBone site. You'll have to work with your ISP
to trace the packets back to the source.
Is this a host or network firewall? If it's a host firewall, the source may
very well be internal to your own network.
