Anti-Dos precedures.

My comerades run a web-hosting service....seen here <br />
<A HREF="http://www.l33t.ca">L33t.ca</a><br />
anyways they have been having quite a bit of difficulty from a individual, or possibly a group (im unsure i still have yet to examine the logs) with dos.  I know how to deal with syn/ syn/ack based attacks, and other than that ddos is simple enough to deal with,  but supposing their using the least likely (icmp ip rebroadcast dos) i was wondering how to deal with an attack like that.
I plan to set a strict set of rules at the router, and i may only allw icmp from trusted networks... only if it comes to that.

thanks for your help.

well we use the razor-team's ddos tracker to stop the mass ddos movement.  as for blocking the isp:  thats entirely out of the question,  if you viewed the site itself you would have noted its a web host and banning the entirety of an isp would not only make us lose customers it would limit current customers potential growth... hence why i am in a bit of a bind.  unless i block individual ip's (which are nearly limitless) im out of options m i not?.
