This chapter introduces the main features and applications of the ZyWALL.
1.1

ZyWALL 70 Internet Security Appliance Overview

The ZyWALL 70 Internet security gateway is designed for medium sized business that need
the increased throughput and reliability of dual WAN ports and load balancing. 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.
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 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.

1.2 Physical Features

LAN Port
The 10/100 Mbps auto-negotiating Ethernet LAN port allows the ZyWALL to detect the speed
of incoming transmissions and adjust appropriately without manual intervention. It allows data
transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending
on your Ethernet network. The port is also auto-crossover (MDI/MDI-X) meaning it
automatically adjusts to either a crossover or straight-through Ethernet cable.
DMZ Ports
Public servers (Web, FTP, etc.) attached to a DeMilitarized Zone (DMZ) port are visible to the
outside world (while still being protected from DoS (Denial of Service) attacks such as SYN
flooding and Ping of Death) and can also be accessed from the secure LAN.
