DESCRIPTION
Internet Control Message Protocol is a message control and error-
reporting protocol between a host server and a gateway to the Internet.

processed by the TCP/IP software and directly apparent to the
application user.
The ZyXEL Device will not respond to any incoming Ping requests when
Disable is selected. Select LAN to reply to incoming LAN Ping requests.
Select WAN to reply to incoming WAN Ping requests. Otherwise select
