USING THE WEB-BASED ADVANCED USER INTERFACE
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 the level of security of your Router.
(1)
To turn off the ping response, select "Block ICMP Ping" (1) and click "Apply
Changes". The Router will not respond to an ICMP ping.
