Re: blocking ping reply

I use 3 PCs on a home wireless network protected by Zone Alarm (free

Zone, plus a router.

I tested my PC security using the GRC tests and passed except for
one that I do not know what to do about:

"Ping Reply: RECEIVED (FAILED) - Your system REPLIED to our Ping
(ICMP Echo) requests, making it visible on the Internet. Most
personal firewalls can be configured to block, drop, and ignore
such ping requests in order to better hide systems from hackers.
This is highly recommended since "Ping" is among the oldest and
most common methods used to locate systems prior to further
exploitation."
I am not sure where to correct that ping reply problem. Maybe ping
is needed for my
wireless home network to work.

Appreciate help and advice.

If an external test showed your system replied to a PING and you have the
setup you have given (with the router providing the access to the external
world) then the configuration of your router is allowing the ping reply. If
you feel the need to change this - check the configuration for said router
in the manual (online - manufacturer's web site - support section) for
whatever router you have and act accordingly.

It has nothing (or little) to do with your internal private network and
should not be required for much of anything to work.
