ZyWALL 2WG User’s Guide

This chapter introduces the main features and applications of the ZyWALL.

The ZyWALL is loaded with security features including VPN, firewall, content filtering and 
certificates. The ZyWALL’s De-Militarized Zone (DMZ) increases LAN security by providing 
separate ports for connecting publicly accessible servers. The ZyWALL is designed for small 
and medium sized business that need the increased throughput and reliability of dual WAN 
interfaces and load balancing.

 

The ZyWALL provides the option to change port roles from 

LAN to DMZ.
You can also deploy the ZyWALL as a transparent firewall in an existing network with 
minimal configuration.
The ZyWALL provides bandwidth management, NAT, port forwarding, policy routing, DHCP 
server and many other powerful features.
The ZyWALL has a built-in wireless card that allows IEEE 802.11a, IEEE 802.11b or IEEE 
802.11g compatible clients to securely communicate with the ZyWALL and access the wired 
network behind it. You can use the wireless card as part of the LAN, DMZ or WLAN. 

Note: Only use firmware for your ZyWALL’s specific model.

See 

 for a complete list of features.

Here are some examples of what you can do with your ZyWALL.

Insert a 3G card to have the ZyWALL (in router mode) wirelessly access the Internet via a 3G 
base station. See 

 for more information about 3G.

With both the primary WAN (physical WAN port) and 3G WAN connections enabled, you can 
use load balancing to improve quality of service and maximize bandwidth utilization or set 
one of the WAN connections as a backup.
