ZyWALL 5 Internet Security Appliance Overview

The ZyWALL 5 Internet security gateway is designed for medium sized business that need the
increased reliability of dial backup and traffic redirect. The ZyWALL is loaded with security
features including VPN, firewall, content filtering, and certificates. The ZyWALL increases
network security by adding the option to change port roles from LAN to DMZ (De-Militarized
Zone) for connecting publicly accessible servers.
You can also deploy the ZyWALL as a transparent firewall in an existing network with
minimal configuration.
The ZyWALL also provides bandwidth management, NAT, port forwarding, 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.

1.2.1 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
