#2 That site only checks TCP and you respond to ping/trace route.
There is also UDP. Which could mean that your TCP ports come back as stealth/filtered/time out, but the UDP ports could be open...

"By default, incoming ICMP echo requests are allowed through the firewall, and all other ICMP messages are blocked. This is because the Ping tool is routinely used to send echo request messages for troubleshooting purposes. However, hackers can also send echo request messages to locate target hosts. You can block echo request messages (or unblock other ICMP messages if they're needed for diagnostic purposes) through the Advanced tab on the basic configuration interface."
It appears to me, that I have no reason to worry about the failed ping test provided by Gibson Research, but it will provide an in- centive for me to dig deeper into Internet Protocols using the sites provided by you and westcom. I also need to go deeper into the advanced features of my Robotics 8054 router.
My concern was not so much with not passing the test but
with the implications of being able to be "pinged" on the
net. The mentioned site makes it appear as though it was
undesirable to be pinged even though all the ports checked
on my PC where in stealth mode.
If security was so important, well, PING other computers yourself. A few will not respond. Most will. Its not a serious concern. If blocked, the diagnostics abilities of ping are lost. Do you need them? Yes until you learn how useful it is to you.
