Getting Started Guide

CONNECTING THE DEVICE

Use the network diagram above and the instructions below to connect and set up the

SSG 20 device to protect your network. Use the LEDs on the front panel of the device to

help you determine its status.

Step 1

Connect the workstation to the device using either of the following

methods:

•Connect an Ethernet cable from one of the Trusted ports labeled

0/2 — 0/4 to the Ethernet port on the workstation.

(We recommend this connection method.)

•Connect a straight-through serial cable from the console port to

the supplied DB-9 adapter which then connects to the serial

port on the workstation.

Step 2

Connect the device to a power source using the supplied power

cable. (We recommend using a surge protector.) Confirm that the

following LEDs are working correctly:

a. Ensure that the POWER LED glows green. This indicates that the

device is receiving power.

b. After the device starts (about 2 minutes), ensure that the

STATUS LED blinks green. This indicates that the device is

operating normally.

c. Ensure that the Link Activity LEDs glow green for the connected

Ethernet ports. This indicates that the device has network

connectivity.

Step 3

Configure the workstation to access the device through a browser:

a. Ensure that the workstation is properly connected to the device

using one of the methods presented in step 1.

b. Change the TCP/IP settings of the workstation to automatically

obtain its IP address from the device using DHCP. For help, see

the operating system documentation for the workstation.

Note: Ensure that your internal network does not already have a

DHCP server.

c. If necessary, restart the workstation to enable the changes to

take effect.

You can use the Initial Configuration Wizard (ICW) to configure the

SSG 20 device. Before starting the ICW, decide how you want to

deploy your device. (For additional information, see the SSG 20

Hardware Installation and Configuration Guide.)

Getting Started

Use the instructions in this guide to help you connect your Secure Services Gateway (SSG) 20 device to

your network. For additional configuration information, see the SSG 20 Hardware Installation and

Configuration Guide. (This guide uses the SSG 20-WLAN to illustrate basic network connectivity.)

Getting Started Guide

CONFIGURING THE DEVICE

Use the instructions below to start the Initial Configuration Wizard (ICW), which helps

you to configure the device to protect your network.

Step 1

Launch a browser. In the URL address field, enter

http://192.168.1.1. The Rapid Deployment Wizard window

appears. (The default login admin name and password is

netscreen.)

Note: You can access the ICW from Ethernet ports 0/2 — 0/4,

which are bound to the Trust security zone.

Step 2

If your network uses Juniper Networks NetScreen-Security Manager,

you can use a Rapid Deployment configlet to automatically configure

the device. Obtain a configlet from your NetScreen-Security

Manager administrator, select the Yes option, select the Load

Configlet from: option, browse to the file location, then click Next.

The configlet sets up the device for you.

If you want to bypass the ICW and go directly to the WebUI, select

the last option, then click Next.

If you are not using a configlet to configure the device and want to

use the ICW, select the first option, then click Next. The Initial

Configuration Wizard welcome screen appears. Click Next.

To configure your device with the WebUI or ICW, refer to the

SSG 20 Hardware Installation and Configuration Guide.

By default the ethernet0/2 — ethernet0/4 interfaces are bound to

the bridge group bgroup0 and they all share the IP address

192.168.1.1/24. You can connect the SSG 20 device to your

trusted network with any of the ports bound to this bgroup.

To change the interface bindings, refer to the SSG 20 Hardware

Installation and Configuration Guide.

The following table explains the default interface-to-zone bindings.
