Blocking an ICMP Ping
Compute r 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 Route r’s
security level.

To turn off the ping response, select “Block ICMP Ping” (1) and click
“Apply Changes”. The Router will not respond to an ICMP ping.
