Blocking an ICMP Ping
Computer hackers use what is known as “pinging” to find potential victims on the Internet. By
pinging a specific IP address and receiving a response from the IP address, a hacker can
determine that something of interest might be there. The Router can be set up so it will not
respond to an ICMP ping from the outside. This heightens your Router’s security level.
