Thanks for the reply Alex.

I'll try to modify IPOutgoingPacket() to support the sending of multicast 
packets. If anyone knows of another way of sending multicast packets, please 
don't hesitate to let us know.

IPOutgoingPacket() is probably treating as any other IP
address since multicasting isn't implemented, which is why it sends
out the ARP packets.
