Unfortunately, this smurf business may be old, but not gone.. Worst part is due to the nature of these attacks, you can't find the real source ip's - (thank the irc script-kiddies obviously.. who else would be so bored?) - they are apparently using these (and probably other) networks as 'smurf amplifiers'::

Sean,
I see about 50+ of these a day if I leave my PC on all the time....of course they are alwasy stopped by my firewall, but there still annoying because they fill up my logs. I see them from all different IP's even though I just recently moved myself into a new Class C netblock (no one else is in it except a Cisco Router). So I would also be interested to know if anyone knows why, just cause it annoying :-P Though I have never bother to check there IP's for location (I know a good chunk of the NEtblocks licensed to my region, so I'll see what I find.
   Are these different IP's in the same Class B as you?

Over the last month, I increasing numbers of Smurf trying to come in on my
home firewall, all on Port 0.  From what I have seen & read, this is a
pretty old vulnerability that has been patched. Is this a new hole? I went
from seeing one in a month to 40 (different IPs) just this weekend over a
72 hr period. All coming from my local area (guessing just on the info that
I pull from GeoBytes.com).

Anyone else seeing this ?

Sean
