Overview
The ZyWALL 5 is a firewall with VPN, bandwidth management, content filtering, anti-spam, anti-virus, IDP
(Intrusion Detection and Protection) and many other features. You can use it as a transparent firewall and not
reconfigure your network nor configure the ZyWALL’s routing features. The ZyWALL increases network
security by adding the option to change port roles from LAN to DMZ for use with publicly accessible servers.
This guide covers the initial connections and configuration needed to start using the ZyWALL in your network.
See the User’s Guide for more information on all features.
You may need your Internet access information.
This guide is divided into the following sections.

Do the following to make hardware connections for initial setup.
1Use an Ethernet cable to connect the LAN/DMZ port to a computer. If you configure these ports as DMZ
ports in the LAN or DMZ screen through the web configurator, you can also use Ethernet cables to connect
public servers (web, e-mail, FTP, etc.) to the LAN/DMZ ports.
2Use another Ethernet cable to connect the WAN port to an Ethernet jack with Internet access.
3Insert the ZyWALL Turbo extension card to use the anti-virus and IDP features or insert a wireless LAN
card to use the wireless LAN feature. See the ZyWALL Turbo Card guide for more information about the
extension card. See the user’s guide about installing a wireless LAN card.
4Use the included power adaptor to connect the power socket (on the rear panel) to a power outlet.

then stays on if the testing is successful. The ACT, CARD, LAN/DMZ and WAN LEDs turn on and stay on
if the corresponding connections are properly made.

5 DMZ
The DeMilitarized Zone (DMZ) allows public servers (web, e-mail, FTP, etc.) to be visible to the outside world
and still have firewall protection from DoS (Denial of Service) attacks.
Unlike the LAN, the ZyWALL does not assign TCP/IP configuration via DHCP to computers connected to the
DMZ ports. Configure the computers with static IP addresses (in the same subnet as the DMZ port's IP
address) and DNS server addresses. Use the ZyWALL's DMZ IP address as the default gateway.
Do the following to configure the DMZ if the ZyWALL is in routing mode.
Note: You do not need to configure DMZ with bridge mode, skip to Section 7.
1Click NETWORK, DMZ in the navigation panel.
