I get this on Sheilds Up Gibson webpage.  I use Bitdfefender Ultimate ,  and they do not seem to be able to give me a solution that works.  I was wondering if anyone on this forum can help me configure this at the router level.    Thanks.   "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."
