between a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP)
datagrams, but the messages are processed by the TCP/IP software and directly apparent
to the application user.
The NBG-418N will not respond to any incoming Ping requests when Disable is selected.
Select Enable to reply to incoming WAN Ping requests.
