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.

ZyWALL Computer Ethernet Cables Power Adaptor

ENGLISH

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.

ENGLISH

5Look at the front panel. The PWR LED turns on. The SYS LED blinks while performing system testing and

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.

2 Accessing the Web Configurator

Use this section to configure the WAN interface for Internet access.

5The HOME screen opens.

The ZyWALL is in router mode by default. Continue to the next step if you want to use routing features

such as NAT, DHCP and VPN.

Go to Section 3 if you prefer to use the ZyWALL as a transparent firewall.

1Launch your web browser. Enter 192.168.1.1 (the

ZyWALL’s default IP address) as the address.

If the login screen does not display, see Section

9.1 to set your computer’s IP address.

2Click Login (the default password 1234 is already

entered).

3Change the login password by entering a new

password and clicking Apply.

4Click Apply to replace the ZyWALL’s default

digital certificate.

ENGLISH

3 Bridge Mode

When you set the ZyWALL to bridge mode, it functions as a transparent firewall. Do the following to set the

ZyWALL to bridge mode.

6Check the Network

Status table. If the

WAN status is not

Down and there is an

IP address, go to

Section 5.

If the WAN status is

Down (or there is not

an IP address), click

Internet Access and

use Section 4 to

configure WAN.

ENGLISH

4 Internet Access Setup and Product Registration

1Click Internet Access in the HOME screen to open the Internet access wizard.

Enter the Internet access information exactly as given to you.

If you were given an IP address to use, select Static in the IP Address Assignment drop-down list box and

enter the information provided.

Note: The fields vary depending on what you select in the Encapsulation field. Fill them in with the

information provided by the ISP or network administrator.

Click Apply when you are done.

1Click MAINTENANCE in

the navigation panel and

then Device Mode.

2Select Bridge and

configure a (static) IP

address subnet mask and

gateway IP address for

the ZyWALL’s LAN, WAN,

DMZ and WLAN

interfaces.

3Click Apply. The ZyWALL

restarts.

Skip to Section 5 if you have

servers that you need to be

accesible from the WAN.

ENGLISH

•PPP over Ethernet or PPTP Encapsulation

Select Nailed-Up when you want your connection up all the time (this could be expensive if your ISP bills you

for Internet usage time instead of a flat monthly fee).

To not have the connection up all the time, specify an idle time-out period (in seconds) in Idle Timeout.

•Ethernet Encapsulation

Configure a Roadrunner service in the

NETWORK WAN screens (use the WAN tab).

ENGLISH

2Click Next to display the screen where you

can register your ZyWALL with myZyXEL.com

(ZyXEL’s online services center) and activate

the free content filtering, anti-spam, anti-virus

and IDP trial applications. Otherwise, click

Skip and then Close to complete Internet

access setup.

Note: Make sure you have installed the ZyWALL Turbo Card before you activate the IDP and anti-virus

subscription services.

Turn the ZyWALL off before you install or remove the ZyWALL Turbo Card.

3If you already have an account at

myZyXEL.com, select Existing

myZyXEL.com account and enter account

information. Otherwise, select New

myZyXEL.com account and fill in the

fields below to create a new account and

4Wait for the registration progress to finish.

ENGLISH

5The following screen displays if the registration

was not successful. Click Return to go back to

the Device Registration screen and check your

settings.

6Click Close to leave the wizard screen when

the registration and activation are done.

Note: If you want to activate a standard

service with your iCard’s PIN number

(license key), use the

REGISTRATION Service screen.

See the user’s guide for details.

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.
