POWER 5VDC Port

Use only the included 5 VDC power adapter or one with the

same specifications.

Connect the female end of the power adapter to the port labeled POWER

5VDC on the rear panel of your ZyWALL.

Additional Installation Requirements

1. A computer(s) with an installed Ethernet NIC (Network Interface Card).

2. A cable/xDSL modem and an ISP account.

Turning on Your ZyWALL

Plug the male end of the power adapter into a power outlet. The SYS LED turns

on. The WAN and the LAN LED(s) turn on after the system tests are complete,

if the WAN and LAN ports are properly connected.

RESET Button

If you forget your password or cannot access the ZyWALL, use the RESET

button on the rear panel of the ZyWALL to reinstall the factory default

configuration (rom) file. Uploading the factory default configuration file

replaces the current configuration file with the default configuration file and

deletes all customer-made ZyWALL configurations. The Password resets to

“1234” and the IP address resets to 192.168.1.1.

Using the RESET Button

1. Use a pointed object to press the RESET button for five seconds, then

release it.

2. If the LAN LEDs flash within 30 seconds, the factory defaults have been

restored and the ZyWALL restarts. Otherwise, go to step 3.

3. Turn the ZyWALL off.

4. While pressing the RESET button, turn the ZyWALL on.

5. Continue to hold the RESET button for about 30 seconds. The ZyWALL

restarts.

6. Release the RESET button and wait about ten seconds for the ZyWALL to

finish restarting.

ZyWALL 1 Internet Security Gateway

Preparing Your Network

Since most Internet/network-related protocols are dependent on TCP/IP, you

need to install and configure TCP/IP on your computer before you can access

the Internet.

Windows 95/98/Me/NT/2000, Macintosh OS 7 and later operating systems and

all versions of UNIX (including Linux) include the software components you

need to install and use TCP/IP on your computer.

After the appropriate TCP/IP components are installed, configure the TCP/IP

settings in order to "communicate" with your network. The ZyWALL assigns

these factory default values if you configure TCP/IP using DHCP:

•IP address: between 192.168.1.33 and 192.168.1.64

•Subnet Mask: 255.255.255.0

•Default Gateway: 192.168.1.1 (the ZyWALL)

Do not assign an arbitrary IP address or subnet mask to

your computer, if you do, you will not be able to access the

Internet.

Windows 95/98/Me

Installing TCP/IP Components

1. Click Start in the task bar (usually in the screen’s lower left-hand corner).

2. Click Settings and then Control Panel.

3. In the Control Panel window, double-click the Network icon.
