Getting to Know Your ZyWALL
This chapter introduces the main features and applications of the ZyWALL.
1.1
ZyWALL Internet Security Appliance Overview
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.

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.

1.2 Applications for the ZyWALL
Here are some examples of what you can do with your ZyWALL.
1.2.1 3G WAN Application
Insert a 3G card to have the ZyWALL (in router mode) wirelessly access the Internet via a 3G
base station. See
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.
