Secure Services Gateway 20

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.)

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:
POWER
STATUS
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.)
