ICMP (Ping)
Respond to
ICMP (ping)
The ICMP protocol is used by the "ping" and "traceroute" programs,
and by network monitoring and diagnostic programs.
If checked, the DSL/Cable Router will repond to ICMP packets
received from the Internet.
If not checked, ICMP packets from the Internet will be ignored.
Disabling this option provides a slight increase in security.
