What are you using for a firewall? Or are you using a router?
Both have options to block or drop icmp traffic.

Subject: [Dshield] ICMP Echo Requests


Firstly can I apologize if this is the wrong place to ask this but I am
unable to get any help from my service provider other than their
suggestion to submit my firewall log files to Dshield which I have been
doing since 9 Dec. but I see that Dshield ignores ICMP entries.

Upto a couple of months ago I had a static IP address and had no
problems but after a technical problem at my SP's end was repaired I
have since had dynamic IP addresses. Very occasionally I get an IP
address where I get no ICMP entries but most days I get approx 17,000
per day.

It appears that my firewall is blocking every attempt and Shields Up
reports that my system is completely Stealthed. I run Norton AV everyday
and have even downloaded and run the FixWelch program from Norton
(reported - "W32.Welchia.Worm has not been found on your computer.").

Do I have anything to worry about? Is there anything I can do to put an
end to all the ICMP traffic?
