Echo ICMP on
LAN Port
The ICMP protocol is used by the "ping" and "trace route" programs,
and by network monitoring and diagnostic programs.
• If checked, the Broadband VPN Gateway will respond 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.
