Getting to Know Your ZyWALL
This chapter introduces the main features and applications of the ZyWALL.
1.1 ZyWALL 35 Internet Security Appliance Overview
The ZyWALL 35 is the ideal secure gateway for all data passing between the Internet and the
LAN.
By integrating NAT, firewall, content filtering, certificates and VPN capability, ZyXEL’s
ZyWALL is a complete security solution that protects your Intranet and efficiently manages
data traffic on your network. Dual WAN ports, dial backup and traffic redirect enhance
reliability. You can deploy the ZyWALL as a transparent firewall in an existing network with
minimal configuration.
The ZyWALL allows you to manage the bandwidth usage of your network's traffic. It also has
two WAN interfaces and can balance the traffic load between them. You can control which IP
addresses and applications get how much bandwidth. You can set priority for different types of
traffic and/or IP addresses. You can also allot bandwidth to specific traffic types to guarantee
delivery.
The PCMCIA/CardBus slot allows you to add a 802.11b/g-compliant wireless LAN. 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. The
ZyWALL increases network security by adding the option to change port roles from LAN to
DMZ (De-Militarized Zone) for use with publicly accessible servers.
The embedded web configurator is easy to operate.
