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 is designed for small and medium sized
business that need the increased throughput and reliability of dual WAN interfaces 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,
DHCP server and many other powerful features.
You can add an IEEE 802.11b/g-compliant wireless LAN by either inserting a wireless LAN
card into the PCMCIA/CardBus slot or connecting an access point (AP) to an Ethernet port in
a WLAN port role. If you insert a wireless LAN card to add a 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. You can use the
wireless card as part of the LAN, DMZ or WLAN.
