Internet Control Message Protocol (ICMP) pings and
traceroute on the PIX Firewall are handled differently
based on the version of PIX and ASA code.

Inbound ICMP through the PIX/ASA is denied by default.
Outbound ICMP is permitted, but the incoming reply is
denied by default.

** ASA/PIX does not support ICMP redirects, because it does
not support asymmetric routing

Answer / sachin

it is used in finding out the error message like if data
gram is not reaching to the destination.It is reliable
protocol as compared to Internet protocol.

Answer / hasan

ICMP works on
echo-request n echo-reply

in network communications devices echo-request/reply's open
open in network security devices echo-request/reply is
close as inbound traffic is restricted by default.

so by this process of echo-request n echo-reply the PING
and traceroute works and gives the information that the
channel is established.
