I recently tested the ESS firewall at GRC. It passed the leak test but on the shields up test it was indicated as not being stealthed due to the following: 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 have previously tested Zone alarm and have had the same result. Can anyone explain to me whey this has occurred and how I can change the ESS firewall so that it is truly stealthed. Much appreciated. So far no probs with this program and I will obtain a copy when it is released. Great work.
