The Zyxel Device sends its external MAC address to the WAN sender as the destination for the target IP
address. From then on the sender will send packets containing that target IP address directly to the
external interface of the Zyxel Device. The Zyxel Device then forwards the packet to the correct target IP
address in its LAN.

DESCRIPTION
Interface Name
This identifies the interface for which the configuration settings that use it are displayed.
Address Type
Choose
IPv4 Address
, or
IPv4 CIDR
(for example, 192.168.1.1/24) or an
IPv4 Range
(for
example, 192.168.1.2-192.168.1.100) and then enter the target IP address information. The
Zyxel Device answers external ARP requests only if they match one of these inputted target IP
addresses. For example, if the
IPv4 Address
is 192.168.1.5, then the Zyxel Device will answer
ARP requests coming from the WAN only if it contains 192.168.1.5 as the target IP address.
