ZyWALL 2

1 Introducing the ZyWALL

The ZyWALL 2 is the ideal secure gateway for all data passing between the Internet and the LAN.

By integrating NAT, firewall and VPN capability, ZyXEL’s ZyWALL 2 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.

2 Hardware

This section provides details on hardware specifications.

ZyWALL 2

2.1 Rear Panel

LABEL DESCRIPTION

1. LAN 10/100M 1-

Connect a computer to one of these ports with an Ethernet cable. These ports are auto-

negotiating (can connect at 10 or 100Mbps) and auto-sensing (automatically adjust to

the type of Ethernet cable you use (straight-through or crossover).

2. WAN 10/100M Connect your cable/DSL modem to this port with the cable that came with your modem.

3. POWER 12

VDC

Connect the included power adaptor (use only this adapter) to this power socket.

After you’ve made the connections, connect the power cable to a power supply and look at the front panel LEDs.

CON/AUX switch

CON/AUX port

Only connect this port if you want to configure the ZyWALL using the SMT via console

port or set up a backup WAN connection; see your User’s Guide for details.

Set this switch to the “CON” side to use the CON/AUX port as a console port for local

device configuration and management. 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.

Set this switch to the “AUX” side to use the CON/AUX port as an auxiliary dial-up WAN

connection. Use the included CON/AUX converter, with the console cable to connect

the CON/AUX port to your modem or TA.

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).

2.2 The Front Panel LEDs

The PWR LED turns on when you connect the power. The SYS LED blinks while performing

system testing and then stays on if the testing is successful. The CON/AUX, LAN, and WAN LEDs

turn on if the ports are properly connected.

3 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.

3.1 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.

ZyWALL 2

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.

ZyWALL 2

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.

4 Configuring Your ZyWALL

This Compact Guide shows you how to use the web configurator wizard

only. See your User’s Guide for background information on all ZyWALL

features and System Management Terminal (SMT) configuration.
