It's a fairly minor "problem." Some would not even consider it a problem at
all.

Are you using a router or are you directly plugged to the cable modem? If
you have a router, then it is responding to the pings. The ShieldsUp site
is actually talking to your router, and your PC is safely hidden behind the
router.

ZoneAlarm Pro, in its default configuration, does block replies to "pings"
as far as I know. Unfortunately, I don't have it so I can't test that.
