What he's saying is that someone is mounting broadcast ping flooding

mmmm... no.  The forged source address is that of the victim.  The listed 
broadcast addresses are the destinations of the packets with the forged 
address of the victim.  The broadcast addresses are never forged.

Really?  

Hmmm...

In any event, such filtering on the part of IAP's will solve the
