Network Address
Translation (NAT)
Each computer on your network must have its own unique IP
address. Use NAT to convert your public IP address(es) to
multiple private IP addresses for
the computers on your
network.
Port Forwarding
If you have a server (mail or web server for example) on your
network, you can use this feature to let people access it from
the Internet.
DHCP (Dynamic Host
Configuration Protocol)
Off by default. Use this feature to have the ZyXEL Device
assign IP addresses, an IP default gateway and DNS servers to
computers on your network. Your device can also act as a
surrogate DHCP server (DHCP Relay) where it relays IP address
assignment from the actual real DHCP server to the clients.
Relay - Supports up to five (5) IP addresses from a remote
DHCP server.
Server - Configurable IP address pool and limits on number of
DHCP clients.

use a fixed URL, www.zyxel.com for example, with a dynamic
IP address. You must register for this service with a Dynamic
DNS service provider.
IP Multicast
IP multicast is used to send traffic to a specific group of
computers. The ZyXEL Device supports IGMP (Internet Group
Management Protocol) used to join multicast groups (see RFC

site and use the web configurator to put it on the ZyXEL
Device.

Restore

Logs

Device to an external syslog server.

networks over the same Ethernet interface. Your device
supports three logical LAN interfaces via its single physical
Ethernet interface with the your device itself as the gateway for
each LAN network.
