Grounding Lug
A one-hole grounding lug is provided on the rear of the chassis to connect the
device to earth ground (see Figure 5).
To ground the device before connecting power, you connect a grounding cable to
earth ground and then attach the cable to the lug on the rear of the chassis.
Antennae Types
The SSG 5-WLAN devices support three types of custom-built radio antennae:
Diversity antennae — The diversity antennae provide 2dBi omnidirectional
coverage and a fairly uniform level of signal strength within the area of
coverage and are suitable for most installations. this type of antennae are
shipped with the device.
External omnidirectional antenna — The external antenna provides 2dBi
omnidirectional coverage. Unlike diversity antennae, which function as a pair,
an external antenna operates to eliminate an echo effect that can sometimes
occur from slightly delayed characteristics in signal reception when two are in
use.
External directional antenna — The external directional antenna provides
2dBi unidirectional coverage and is well suited for such places as hallways and
outer walls (with the antenna facing inward).
Universal Serial Bus (USB) Host Module
The slot labeled USB on the back panel of an SSG 5 device implements a host-only
USB 1.1 host module for a USB device adapter or USB flash key, as defined in the
CompactFlash Specification published by the CompactFlash Association. When the
USB storage device, or flash key, is installed and configured, it automatically acts as
a secondary storage device.
The USB host module allows file transfers, such as device configurations, user
certifications, and update version images between an external USB flash key and
the internal flash storage located in the security device. The USB host module
supports USB 2.0 specification at either low-speed (1.5M) or full-speed (12M) file
transfer.
To use a USB flash key to transfer files between the device, perform the following
steps:
1. Insert the USB flash key into the USB host module on the security device.
2. Save the files from the USB flash key to the internal flash storage on the device
with the save { software | config | image-key } from usb filename to flash CLI
command.
3. Before removing the USB flash key, stop the host module with the exec
usb-device stop CLI command.
4. It is now safe to remove the USB flash key.
Back Panel 7
To save files from a USB flash key to the device, use the save { software | config |
image-key } from usb filename to flash CLI command.
If you want to delete a file from the USB flash key, use the delete file path:/filename
CLI command.
If you want to view the saved file information on the USB flash key or internal flash
storage, use the get file info CLI command.

Connecting Interface Cables to the Device 11
Connecting Interface Cables to the Device
To connect interface cables to the device:
1. Have ready a length of the type of cable used by the interface.
2. Insert the cable connector into the cable connector port on the device.
3. Arrange the cable as follows to prevent it from dislodging or developing stress
points:
a. Secure the cable so that it is not supporting its own weight as it hangs to
the floor.
b. Place excess cable out of the way in a neatly coiled loop.
c. Place fasteners on the loop to help maintain its shape.
Chassis Grounding
To meet safety and electromagnetic interference (EMI) requirements, and to ensure
proper operation, the SSG device must be adequately grounded before power is
connected. A one-hole grounding lug is provided on the rear of the chassis to
connect the device to earth ground (see Figure 5 on page 5).
The grounding cable must be American Wire Gauge (AWG) number 14 single-strand
wire cable and must be able to handle up to 6 ampere (A).
To ground the device before connecting power, you connect the grounding cable to
earth ground and then attach the cable to the lug on the rear of the chassis.
Connecting the Power
To connect the power to an SSG 5 device, plug the AC adapter end of the power
cable into an AC power source and the power cord into the power outlet. We
recommend using a surge protector for the power connection.
CAUTION: Before device installation begins, a licensed electrician must attach a
cable lug to the grounding cable that you supply. A cable with an incorrectly
attached lug can damage the device (for example, by causing a short circuit).

Default Device Settings 19
Default Device Settings
This section describes the default settings and operation of an SSG 5 device.
Table 4 describes the default zone bindings for ports on the devices.
Table 4: Default Physical Interface to Zone Bindings
A bridge group, bgroup, is designed to allow network users to switch between
wired/wireless traffic without having to reconfigure or reboot the device. By default,
the ethernet0/2—ethernet0/6 interfaces, labeled as port 0/2—0/6 on the device, are
grouped together as the bgroup0 interface, have the IP address 192.168.1.1/24, and
are bound to the Trust security zone. You can configure up to four bgroups.
If you want to set an Ethernet or wireless interface into a bgroup, you must first
make sure that the Ethernet or wireless interface is in the Null security zone.
Unsetting the Ethernet or wireless interface that is in a bgroup places the interface
in the Null security zone. Once assigned to the Null security zone, the Ethernet
interface can be bound to a security zone and assigned a different IP address.
To unset ethernet0/3 from bgroup0 and assign it to the Trust zone with a static IP
address of 192.168.3.1/24, do the following:
unset interface bgroup0 port ethernet0/3
set interface ethernet0/3 zone trust
set interface ethernet0/3 ip 192.168.3.1/24

22 Basic Device Configuration
Setting the Date and Time
The time set on an SSG 5 device affects events such as the setup of VPN tunnels.
The easiest way to set the date and time on the device is to use the WebUI to
synchronize the device system clock with the workstation clock.
WebUI
1. Configuration > Date/Time: Click the Sync Clock with Client button.
A pop-up message prompts you to specify if you have enabled the daylight
saving time option on your workstation clock.
2. Click Yes to synchronize the system clock and adjust it according to
daylight saving time or click No to synchronize the system clock without
adjusting for daylight saving time.
You can also use the set clock CLI command in a Telnet or Console session to
manually enter the date and time for the SSG device.
Bridge Group Interfaces
By default, the SSG 5 devices have Ethernet interfaces ethernet0/2—ethernet0/6
grouped together in the Trust security zone. Grouping interfaces sets interfaces in
one subnet. You can unset an interface from a group and assign it to a different
security zone. Interfaces must be in the Null security zone before they can be
assigned to a group. To place a grouped interface in the Null security zone, use the
unset interface interface port interface CLI command.
The SSG 5-WLAN devices allow Ethernet and wireless interfaces to be grouped
under one subnet.
To configure a group with Ethernet and wireless interfaces, do the following:
unset interface bgroup0 port ethernet0/3
unset interface bgroup0 port ethernet0/4
set interface bgroup1 port ethernet0/3
set interface bgroup1 port ethernet0/4
set interface bgroup1 port wireless0/2
set interface bgroup1 zone DMZ
set interface bgroup1 ip 10.0.0.1/24
save
NOTE: Only wireless and Ethernet interfaces can be set in a bridge group.
Basic Device Configuration 23
Administrative Access
By default, anyone in your network can manage a device if they know the login and
password. You can configure the device to be managed only from a specific host on
your network:
WebUI
Configuration > Admin > Permitted IPs: Enter the following, click Add:
IP Address/Netmask: ip_addr/mask
CLI

Management Interface Address
The Trust interface has the default IP address 192.168.1.1/24 and is configured for
management services. If you connect the 0/2—0/6 port on the device to a
workstation, you can configure the device from a workstation in the 192.168.1.1/24
subnetwork using a management service such as Telnet.
You can change the default IP address on the trust interface. For example, you
might want to change the interface to match IP addresses that already exist on your
LAN.
Backup Untrust Interface Configuration
The SSG 5 devices allow you to configure a backup interface for untrust failover. To
set a backup interface for untrust failover, perform the following steps:
1. Set the backup interface in the Null security zone with the unset interface
interface [ port interface ] CLI command.
2. Bind the backup interface to the same security zone as the primary interface
with the set interface interface zone zone_name CLI command.
To set the ethernet0/4 interface as the backup interface to the ethernet0/0 interface,
do either of the following:
NOTE: The primary and backup interfaces must be in the same security zone. One
primary interface has only one backup interface, and one backup interface has
only one primary interface.

Wireless Configuration
This section provides information for configuring the wireless interface on the
SSG 5-WLAN devices. To use the wireless local area network (WLAN) capabilities on
the device, you must configure at least one Service Set Identifier (SSID) and bind it
to a wireless interface.
Figure 8 shows the default configuration for an SSG 5-WLAN device.
NOTE: If you are operating the SSG 5-WLAN device in a country other than the United
States or Japan, then you must use the set wlan country-code command before a
WLAN connection can be established. This command sets the selectable channel
range and transmit power level.

SSG 5 Hardware Installation and Configuration Guide
26 Wireless Configuration
Figure 8: Default SSG 5-WLAN Configuration
By default, the wireless0/0 interface is configured with the IP address of
192.168.2.1/24. All wireless clients that need to connect to in the Trust zone must
have an IP address in the wireless subnetwork. You can also configure the device to
automatically assign IP addresses in the 192.168.2.1/24 subnetwork to your devices
with DHCP.
By default, the wireless0/1 - wireless0/3 interfaces are defined as Null and do not
have IP addresses assigned to them. If you want to use any of the other wireless
interfaces, you must configure an IP address for it, assign an SSID to it, and bind it
to a security zone.
For more information about WLANs, refer to “Wireless Interface” in the Concepts
and Examples ScreenOS Reference Guide.
Wireless Network Configuration
Wireless networks consist of names referred to as Service Set Identifiers (SSIDs).
Specifying SSIDs allows you to have multiple wireless networks reside in the same
location without interfering with each other. An SSID name can have a maximum of
32 characters. If a space is part of the SSID name string, then the string must be
enclosed with quotation marks. Once the SSID name is set, more SSID attributes
can be configured.
The SSG 5-WLAN devices allow you to create up to 16 SSIDs, but only 4 of them can
be used simultaneously. You can configure the device to use the 4 SSIDs on either
one of the transceivers or split the use on both. For example, 3 SSIDs assigned to
WLAN 0 and 1 SSID assigned to WLAN 1. Use the set interface wireless_interface
wlan { 0 | 1 | both } CLI command to set the radio transceivers on the SSG 5-WLAN
devices.
To set the SSID name netscreen open, allow the SSID to be open to all users, bind
the SSID to the wireless0/0 interface, and use both radio transceivers, do either of
the following:

This section explains how to configure the WAN interfaces:
“The ISDN Interface” on this page
“The V.92 Modem Interface” on page 30
The ISDN Interface
Integrated Services Digital Network (ISDN) is a set of standards for digital
transmission over different media created by the Consultative Committee for
International Telegraphy and Telephone (CCITT) and International
Telecommunications Union (ITU). As a dial-on-demand service, it has fast call setup
and low latency as well as the ability to carry high-quality voice, data, and video
transmissions. ISDN is also a circuit-switched service that can be used on both
multipoint and point-to-point connections. ISDN provides a service router with a
backup connection for network interfaces.
Some SSG 5 devices support ISDN basic rate interfaces (BRIs). The ISDN interface is
usually configured as the backup interface of the Ethernet interface to access
external networks.
To configure the ISDN interface, do either of the following:
WebUI
Network > Interfaces > Edit (bri0/0): Enter or select the applicable option
value, then click OK.
BRI Mode: Dial Using BRI
Primary Number: 123456

The V.92 Modem Interface
Some SSG 5 devices provide an internal modem to establish a PPP connection to an
ISP. You can configure the serial interface as a primary or backup interface, which is
used in case of interface failover.
To configure the V.92 interface, do either of the following:
WebUI
Network > Interfaces > Edit (for serial0/0) > Modem: Enter the following,
click OK:
Modem Name: mod1

CLI
set interface serial0/0 modem idle-time 20
set interface serial0/0 modem settings mod1 init-strings AT&FS7=255S32=6
set interface serial0/0 modem settings mod1 active
For information on how to configure the V.92 modem interface, refer to the
Concepts and Examples ScreenOS Reference Guide.
Basic Firewall Protections
The devices are configured with a default policy that permits workstations in the
Trust zone of your network to access any resource in the Untrust security zone,
while outside computers are not allowed to access or start sessions with your
workstations. You can configure policies that direct the device to permit outside
computers to start specific kinds of sessions with your computers. For information
about creating or modifying policies, refer to the Concepts and Examples ScreenOS
Reference Guide.
The SSG 5 devices provide various detection methods and defense mechanisms to
combat probes and attacks aimed at compromising or harming a network or
network resource:
ScreenOS SCREEN options secure a zone by inspecting, and then allowing or
denying, all connection attempts that require crossing an interface to that zone.
For example, you can apply port scan protection on the Untrust zone to stop a
source from an remote network from trying to identify services to target for
further attacks.
The device applies firewall policies, which can contain content filtering and
intrusion detection and prevention (IDP) components, to the traffic that passes
the SCREEN filters from one zone to another. By default, no traffic is permitted
to pass through the device from one zone to another. To permit traffic to cross
the device from one zone to another, you must create a policy that overrides the
default behavior.
NOTE: The V.92 interface does not work in transparent mode.
Verifying External Connectivity 31
To set ScreenOS SCREEN options for a zone:
WebUI
Screening > Screen: Select the zone to which the options apply. Select the

start a Web browser from any workstation in the network and enter the following
URL: www.juniper.net.
Resetting the Device to Factory Defaults
If you lose the admin password, you can reset the SSG 5 device to its default
settings. This action destroys any existing configurations but restores access to the
device.
You can restore the device to its default settings in one of the following ways:
Using a Console connection. For further information, see the Administration
chapter in the Administration volume of the Concepts and Examples ScreenOS
Reference Guide.
Using the reset pinhole on the front panel of the device, as described in the
next section.
WARNING: Resetting the device deletes all existing configuration settings and
renders existing firewall and VPN service inoperative.
SSG 5 Hardware Installation and Configuration Guide
32 Resetting the Device to Factory Defaults
The Reset Pinhole
You can reset the device and restore the factory default settings by pressing the
reset pinhole. To perform this operation, you need to either view the device status
LEDs on the front panel or start a Console session as described in Using a Console
Connection on page 16.
To use the reset pinhole to reset and restore the default settings, perform the
following steps:
1. Locate the reset pinhole on the rear panel. Using a thin, firm wire (such as a
paper clip), push the pinhole for four to six seconds and then release.
The STATUS LED blinks red. A message on the Console states that erasure of the
configuration has started and the system sends an SNMP/SYSLOG alert.
2. Wait for one to two seconds.
After the first reset, the STATUS LED blinks green; the device is now waiting for
the second reset. The Console message now states that the device is waiting for
a second confirmation.
3. Push the reset pinhole again for four to six seconds.
The Console message verifies the second reset. The STATUS LED glows red for
one-half second and then returns to the blinking green state.
The device then resets to its original factory settings. When the device resets,
the STATUS LED glows red for one-half second and then glows green. The
Console displays device bootup messages. The system generates SNMP and
SYSLOG alerts to configured SYSLOG or SNMP trap hosts.
After the device has rebooted, the Console displays the login prompt for the
device. The STATUS LED blinks green. The login for username and password is
netscreen.
If you do not follow the complete sequence, the reset process cancels without any
configuration change and the console message states that the erasure of the
configuration is aborted. The STATUS LED returns to blinking green. If the device
did not reset, an SNMP alert is sent to confirm the failure.
