The GRC page talks about his dos attack, and he also rants about the 
"dangers" of the IP stack in XP, but his dos attack didn't come from sources 
sending spoofed packets, so source address filtering wouldn't have helped in 
this case.  GRC complaining about the spoofed packet problem should be a 
separate rant on his website (who probably is!).
