Hey everyone. I went to GRC to test my ports and everything was green and closed except at the very end of the test it said "failed" and the message was...

"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."

Now I already have the firewall turned on in snow leopard and i know GRC doesn't test them on the mac but on the router i think but what does this mean?
Is there something on my Airport Extreme that I need to enable??? or does this even matter?

    I wouldn't worry about it. Even if you change that behavior (which I don't think you can do), it doesn't make you any more vulnerable.
