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.

Thank you. I will look at my router's settings. The message from
GRC.com was that the setting was in the firewall. In my case that is
Zone Alarm Free and I did not find where to change that there.

Thanks for the explanation.
