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 and
certificates. 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, DHCP server and many other powerful features.

1.2 Physical Features

4-port LAN Switch
A combination of switch and router makes your ZyWALL a cost-effective and viable network
solution. You can connect up to four computers to the ZyWALL without the cost of a hub. Use
a hub to add more than four computers to your LAN.
WAN
The Ethernet WAN port connects to the Internet via broadband modem or router.
Auto-negotiating 10/100 Mbps Ethernet Ports
All of the ZyWALL's Ethernet ports are 10/100 Mbps auto-negotiating. This allows the
ZyWALL to detect the speed of incoming transmissions and adjust appropriately without
manual intervention. They allow data transfers of either 10 Mbps or 100 Mbps in either half-
duplex or full-duplex mode depending on your Ethernet network. The ports are also auto-
crossover (MDI/MDI-X) meaning they automatically adjust to either a crossover or straight-
through Ethernet cable.
Dial Backup WAN
The dial backup port can be used in reserve as a traditional dial-up connection if the WAN and
traffic redirect connections fail.
