CHAPTER 1
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, anti-
spam, IDP (Intrusion Detection and Prevention), anti-virus and certificates. The ZyWALL’s
De-Militarized Zone (DMZ) increases LAN security by providing separate ports for
connecting publicly accessible servers. The ZyWALL 70 and ZyWALL 35 are designed for
medium sized business that need the increased throughput and reliability of dual WAN ports
and load balancing. The ZyWALL 35 and ZyWALL 5 provide 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 (not
available for the ZyWALL 5), DHCP server and many other powerful features.
The PCMCIA/CardBus slot allows you to add a 802.11b/g-compliant wireless LAN. You can
use the wireless card as part of the LAN, DMZ or WLAN. The ZyWALL offers highly secured
wireless connectivity to your wired network with IEEE 802.1x, WEP data encryption, WPA
(Wi-Fi Protected Access) and MAC address filtering.
