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 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, DHCP server and
many other powerful features.
You can add an IEEE 802.11a/b/g-compliant wireless LAN by connecting an access point
(AP) to an Ethernet port in a WLAN port role.
