Introducing the ZyWALL
The ZyWALL 35 is the ideal secure gateway for all data passing between the Internet and the LAN. By
integrating NAT, firewall, content filtering, certificates and VPN capability, ZyXEL’s ZyWALL 35 is a
complete security solution that protects your Intranet and efficiently manages data traffic on your network.
The ZyWALL increases network security by adding up to four De-Militarized Zone (DMZ) ports for use
with publicly accessible servers. Dual WAN ports and dial backup enhance reliability. The
PCMCIA/CardBus slot allows you to add a 802.11b/g-compliant wireless LAN. 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.

came with your modem(s).
2. Connect computers or hubs to LAN ports with Ethernet cables.
If you configure these ports as DMZ ports in the LAN or DMZ screen through the Web configurator,
connect publicly accessible servers (Web, FTP, etc.) to these ports to make them visible to the outside
world.

4. If you want to set up a backup WAN connection, connect the 9-pin female end of your modem or
Terminal Adaptor (TA) cable to DIAL BACKUP port and the other end to your modem or TA.
5. If you want to configure the ZyWALL using the SMT (System Management Terminal) via CONSOLE
port, 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.
6. After you’ve made the connections, connect the included power adaptor to the power socket and
connect the power adaptor to a power supply (outlet).
The PWR LED turns on green when you connect the power. The SYS LED blinks for about 30 seconds
while performing system testing and then stays on if the testing is successful. The ACT, CARD, WAN

2 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.

3. Right-click Local Area Connection and then click Properties.
4. Select Internet Protocol (TCP/IP) (under the General tab in Windows 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.

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.
