Introducing the ZyWALL
The ZyWALL 100 is the ideal secure gateway for all data passing between the Internet and the LAN. By
integrating NAT, firewall, VPN capability and wireless LAN, ZyXEL’s ZyWALL 100 is a complete security
solution that protects your Intranet and efficiently manages data traffic on your network. The embedded web
configurator is easy to operate and totally independent of the operating system platform you use.
You should have an Internet account already set up and have been given most of the following information.

LABEL DESCRIPTION
1. LAN 10/100M Connect a computer to this port with an Ethernet cable. This port is auto-negotiating (can
connect at 10 or 100Mbps). Push the UPLINK button in with a straight-through Ethernet cable or
have the UPLINK button out with a crossover Ethernet cable.
2. WAN 10/100M Connect your cable/DSL modem to this port with the cable that came with your modem.
3. POWER 100-
240VAC
Connect the included power cord (use only this cord) to this power socket.
After you’ve made the connections, connect the power cord to a power supply and push the power switch to the on position.
Look at the front panel LEDs.
CONSOLE Only connect this port if you want to configure the ZyWALL using the SMT via console port; see
your User’s Guide for details.
Connect the 9-pin male end of the console cable to the console port of the ZyWALL and the
other end to a serial port (COM1, COM2 or other COM port) on your computer. Your computer
should have a terminal emulation communications program (such as HyperTerminal) set to
VT100 terminal emulation, no parity, 8 data bits, 1 stop bit, no flow control and 9600 bps port
speed.
DIAL BACKUP
Only connect this port if you want to set up a backup WAN connection; see your User’s Guide for
details.
Connect the 9-pin female end of your modem or TA cable to this port and the other end to your
modem or TA.
DMZ 10/100M Connect publicly accessible servers (Web, FTP, etc.) to this port to make them visible to the
outside world. Use a crossover Ethernet cable to connect this port to a single computer.
For multiple computers, use a straight-through Ethernet cable to connect this port to a hub.
RESET You only need to use this button if you’ve forgotten the ZyWALL’s password. It returns the
ZyWALL to the factory defaults (password is 1234, LAN IP address 192.168.1.1, terminal
emulation settings as described above etc.; see your User’s Guide for details).

Setting Up Your Computer’s IP Address
Skip this section if your computer is already set up to accept a dynamic IP
address. This is the default for most new computers.
The ZyWALL is already set up to assign your computer an IP address. Use this section to set up your
computer to receive an IP address or assign it a static IP address in the 192.168.1.2 to 192.168.1.254 range
with a subnet mask of 255.255.255.0. This is necessary to ensure that your computer can communicate with
your ZyWALL.
Your computer must have an Ethernet card and TCP/IP installed. TCP/IP should already be installed on
computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems.
Windows 2000/NT/XP
1. In Windows XP, click start, Control Panel. In Windows 2000/NT, click Start, Settings, Control Panel.
2. In Windows XP, click Network Connections.
In Windows 2000/NT, click Network and Dial-up Connections.
3. Right-click Local Area Connection and then click Properties.
4. Select Internet Protocol (TCP/IP) (under the General tab in Win XP) and click Properties.

5. The Internet Protocol TCP/IP Properties screen opens (the
General tab in Windows XP).
- To have your computer assigned a dynamic IP address, click
Obtain an IP address automatically.
-To configure a static IP address, click Use the following IP
Address and fill in the IP address (choose one
from192.168.1.2 to 192.168.1.254), Subnet mask
(255.255.255.0), and Default gateway (192.168.1.1) fields.
6. Click Advanced. Remove any previously installed gateways in
the IP Settings tab and click OK to go back to the Internet
Protocol TCP/IP Properties screen.
7. Click Obtain DNS server address automatically if you do
not know your DNS server IP address(es).
If you know your DNS server IP address(es), click Use the
following DNS server addresses, and type them in the
Preferred DNS server and Alternate DNS server fields.
If you have more than two DNS servers, click Advanced, the
DNS tab and then configure them using Add.
8. Click OK to close the Internet Protocol (TCP/IP) Properties
window.
9. Click OK to close the Local Area Connection Properties
window.
Checking Your Computer’s IP Address
1. In the computer, click Start, (All) Programs, Accessories and then Command Prompt.
2. In the Command Prompt window, type "ipconfig" and then press ENTER. Your computer’s IP address must be in
the correct range (192.168.1.2 to 192.168.1.254) with subnet mask 255.255.255.0 in order to communicate with
the ZyWALL.
Refer to your User’s Guide for detailed IP address configuration for other Windows and Macintosh computer
operating systems.

Configuring Your ZyWALL
Choose one of these methods to access and configure the ZyWALL. This Quick
Start Guide shows you how to use the web configurator wizard only. See your
User’s Guide for background information on all ZyWALL features and SMT
configuration. Click the web configurator online help for screen-specific web help.
 Web Configurator
 SMT (System Management Terminal). Access the SMT via:
o Console port using terminal emulation software
o LAN, WLAN or WAN using Telnet
Accessing Your ZyWALL Via Web Configurator
Step 1. Launch your web browser. Enter “192.168.1.1” as the web site address.
Step 2. The default password (“1234”) is already in the password field (in non-readable format). Click
Login to proceed to a screen asking you to change your password. Click Reset to revert to the
default password in the password field.
Step 3. It is highly recommended you change the default password! Enter a new password, retype it to
confirm and click Apply; alternatively click Ignore to proceed to the main menu if you do not
want to change the password now.

Step 4. You should now see the web configurator MAIN MENU screen.
 Click WIZARD to begin a series of screens to help you configure your ZyWALL for the first time.
 Click a link under ADVANCED in the navigation panel to configure that ZyWALL feature.
 Click MAINTENANCE in the navigation panel to see ZyWALL performance statistics, upload
firmware and back up, restore or upload a configuration file.
 Click LOGOUT when you have finished a ZyWALL management session. The ZyWALL
automatically logs you out if it is left idle for five minutes; press ENTER to display the Login
screen again and then log back in. This idle timeout timer is one of the many ZyWALL features that
you may edit using the web configurator.

Step 1. Click Wizard Setup in the main menu to display the first wizard screen.
System Name is for identification purposes.
Enter your computer's "Computer Name".
The Domain Name entry is what is propagated to
the DHCP clients on the LAN. If you leave this
blank, the domain name obtained by DHCP from
the ISP is used. Click Next to continue.
Step 2. The second wizard screen has three variations depending on what encapsulation type you use. Use
the information in Internet Account Information to fill in fields.
Choose Ethernet when the WAN port
is used as a regular Ethernet. Choose
from Standard or a RoadRunner
version. You’ll need User Name,
Password and Login Server IP
Address for some Roadrunner
versions.
Point-to-Point Protocol over Ethernet
(PPPoE) also functions as a dial-up
connection. Therefore you’ll also need
a username and password and
possibly the PPPoE service name.
Your ISP will give you all needed
information.
Choose PPTP if your service provider
uses a DSL terminator with PPTP
login. The ZyWALL must have a static
IP address in this case. You’ll also
need a login name, associated
password, the DSL terminator IP
address and possibly a connection ID.
Click Next to continue.
Step 3. Fill in the fields and click Finish to save and complete the wizard setup.
