I've seen it (I used Section 5 to create my rules).  However, my
computer is stand alone workstation without any servers, but with DLS
connection, so I want to make it run in stealth mode, even unpingbile at
all

ping-o-deth rune is based on the limit.  I tried 

"iptables -A block -p icmp --icmp-type echo-request -j DROP"

but it doesn't work

doesn't work either (till be pingable).

Thanks.
