hmmm...attackers..??

just one thing about blockin,droppin,stealthin(orwhatever) all ICMP traff:
if you are running a webserver you will make any DSL user angry about your shitworking site.
a little problem with lenght of the blocks while usin DSL( sry ,still i do not really understand this ).
the dsl users will only be able to access ya site without errors by coming thru a proxy.
