Connecting the Device
This chapter describes how to connect the NetScreen-5GT Wireless device to the network,
connect the power, and connect an antenna. If you are using the optional NetScreen-5GT
Wireless rack mount kit, then use the rack mounting instructions that are included at the
end of this chapter.
Note: For safety warnings and instructions, refer to the NetScreen Safety Guide. The
instructions in this guide warn you about situations that could cause bodily injury. Before
working on any equipment, be aware of the hazards involved with electrical circuitry and
be familiar with standard practices for preventing accidents.
CONNECTING THE NETSCREEN DEVICE TO YOUR NETWORKS
The NetScreen device provides firewall and general security for your networks when it is
placed between your internal networks and the Untrusted network. This section describes
the physical connections.
Connecting the Device to an Untrusted Network
Depending upon which model of the NetScreen-5GT Wireless device you have, you can
connect to the Untrusted network in one of the following ways:
• Through an ADSL connection from the ADSL port on the NetScreen device.
• Through an Ethernet connection from the Untrusted port on the NetScreen
device.
Connecting the ADSL Port
Connect the provided ADSL cable from the ADSL port on the NetScreen-5GT Wireless
ADSL device to your telephone outlet. The ADSL port on the Annex A version of the
device uses an RJ-11 connector, while the Annex B version uses an RJ-45 connector. In
the case of Annex B models, the cable you connect fr om the ADSL port to the telephone
outlet is identical in appearance and wiring to a straight-through 10 Base-T Ethernet
cable.
Warning: Make sure that you do not inadvertently connect the Console, Modem, or
Ethernet ports on the NetScreen device to the telephone outlet.
NetScreen-5GT Wireless 7
Chapter 1 Connecting the Device
The ADSL line is your primary connection to an outside network. For a backup data link
to an outside network, you can either connect an Ethernet cable from the Untrusted port
on the NetScreen-5GT Wireless ADSL device to an external router, DSL modem, or cable
modem, or connect a serial cable from the Modem port on the device to an external
modem.
Warning: You cannot connect both the Untrusted port and the Modem port on the device
to an outside network at the same time.
Connecting Splitters and Microfilters
A signal splitter divides the telephone signal into low-frequency voice signals for voice
calls and high-frequency data signals for data traffic. Your service provider usually
installs the splitter as part of the equipment that connects your site’s telephone lines to
the provider’s network.
There are also splitters that you may be able to install yourself, depending upon your
service provider equipment. If you are installing such a splitter yourself, then connect the
ADSL cable from the NetScreen device and the telephone line to the appropriate
connectors (for example, “data” or “voice”) on the splitter. You connect the other end of the
splitter to the telephone outlet.
You may need to install a microfilter on each telephone, fax machine, answering machine,
or analog modem that connects to the ADSL line. The microfilter filters out highfrequency noise on the telephone line. You install the microfilter on the telephone line
between the telephone, fax machine, answering machine, or analog modem and the voice
connector on the splitter.
The following shows an example of a microfilter and a splitter that you install on your
site. (You must obtain the appropriate microfilters or splitters from your service provider.)

Chapter 2 Configuring the Device
The NetScreen device allows any type of traffic to the Internet that originates from
devices in your Trust zone, but does not allow any traffic that originates in the Internet to
reach your network. You can configure additional restrictions; refer to “Configuring
Additional Policies” on page 25.
Configuring the ADSL Interface
Your network uses the ADSL interface “adsl1” on the NetScreen device to connect to the
service provider’s network through an Asynchronous Transfer Mode (ATM) virtual circuit.
You can configure additional virtual circuits by creating ADSL subinterfaces (see “Adding
Virtual Circuits to an ADSL Interface” on page 20 for more information).
In the WebUI, navigate to the Network > Interfaces page to see a list of the current
interfaces on the NetScreen device. If you are using a Telnet or Console session, enter the
CLI command get interface. You should see that the adsl1 interface is bound to the
Untrust zone. If you used the Initial Configuration Wizard to configure the device, then
there may be an IP address and netmask already assigned to the adsl1 interface.
Note: If you do not want to use the ADSL interface, then you can bind it to the Null zone
with the set interface adsl1 zone null command. If you use the Initial Configuration
Wizard to configure the device, you can choose to not use the ADSL interface as the default
interface to the Untrust zone.
You must configure the adsl1 interface to enable the NetScreen device to connect to the
service provider’s network. To do this, you must obtain the following informa t io n from
your service provider:
• Virtual Path Identifier and Virtual Channel Identifier (VPI/VCI) values
• Asynchronous Transfer Mode (ATM) Adaptation Layer 5 (AAL5) multiplexing
method, which can be one of the following:
– Virtual Circuit (VC)-based multiplexing, in which each protocol is carried
over a separate ATM virtual circuit
– Logical Link Control (LLC) encapsulation, which allows several protocols
to be carried on the same ATM virtual circuit (this is the default
multiplexing method)
• User name and password assigned by the service provider for connection to the
service provider’s network using either the Point-to-Point Protocol over Ethernet
(PPPoE) or Point-to-Point Protocol over ATM (PPPoA)
• Authentication method, if any, provided for the PPPoE or PPPoA connection
• Optionally, a static IP address and netmask value for your network
Adding Virtual Circuits to an ADSL Interface
To add virtual circuits, you create sub-interfaces to the ADSL interface. You can create up
to ten ADSL subinterfaces. For example, to create a new subinterface adsl1.1 that is
bound to the user-defined zone named “Corp1”:
20 User’s Guide
ADSL Configuration
WebUI
Network > Interfaces > New ADSL Sub-IF: Enter the following, and then click
Apply:
Interface Name: adsl1.1
VPI/VCI: 0/35
Zone Name: Corp1 (select)
CLI
set interface adsl1.1 pvc 0 35 zone corp1
save
You need to configure an ADSL subinterface in the same way as the main ADSL interface,
including setting the VPI/VCI values, as described in “Configuring the ADSL Interface”
on page 20. You configure an ADSL subinterface independently of the main ADSL
interface, that is, you can configure a different multiplexing method, VPI/VCI, and PPP
client on the subinterface than the main ADSL interface. You can also configure a static
IP address on a subinterface, even if the main ADSL interface does not have a static IP
address. Note that a subinterface and the main ADSL interface can use the same VPI/VCI
values if one interface is configured for PPPoA and the other for PPPoE and they both use
LLC multiplexing.
VPI/VCI and Multiplexing Method
Your service provider assigns a VPI/VCI pair for each virtual circuit connection. For
example, you may receive the VPI/VCI pair 1/1, which means a VPI value of 1 and a VCI
value of 1. These values must match the values that the service provider has configured
on the subscriber’s side of the digital subscriber line access multiplexer (DSLAM).
To configure the VPI/VCI pair 1/1 on the adsl1 interface:
WebUI
Network > Interfaces > Edit (for the adsl1 interface): Enter 1/1 in the VPI/VCI
field, and then click Apply.
CLI
set interface adsl1 pvc 1 1
save
By default, the NetScreen-5GT Wireless ADSL device uses LLC-based multiplexing for
each virtual circuit. To configure the VPI/VCI 1/1 on the adsl1 interface and use LLC
encapsulation on the virtual circuit:
WebUI
Network > Interfaces > Edit (for the adsl1 interface): Enter the following, and
then click Apply:
VPI/VCI: 1 / 2
Multiplexing Method: LLC (selected)
NetScreen-5GT Wireless 21

CLI
set interface adsl1 pvc 1 1 mux llc
save
PPPoE or PPPoA
The NetScreen device includes both PPPoE and PPPoA clients to connect to the service
provider’s network over the ADSL link. PPPoE is the most common form of ADSL
encapsulation and is intended for termination on each host on your network. PPPoA is
used primarily for business class service as PPP sessions can be terminated on the
NetScreen device. To allow the NetScreen device to connect to the service provider’s
network, you need to configure the user name and password assigned by the service
provider. The configuration for PPPoA is similar to the configuration for PPPoE.
Note: The NetScreen device supports only one PPPoE session on each virtual circuit.
To configure the user name “roswell” and password “area51” for PPPoE and bind the
PPPoE configuration to the adsl1 interface:
WebUI
Network > PPPoE > New: Enter the following, and then click OK:
PPPoE Instance: poe1
Bound to Interface: adsl1 (select)
Username: roswell
Password: area51
CLI
set pppoe name poe1 username roswell password area51
set pppoe name poe1 interface adsl1
save
There are other PPPoE or PPPoA parameters that you can configure on the NetScreen
device, including method of authentication (by default, the NetScreen device supports
either Challenge Handshake Authentication Protocol or Password Authentication
Protocol), idle timeout (default is 30 minutes), and so on. Ask your service provider if
there are additional PPPoE or PPPoA parameters that you need to configure to enable
proper communications with the service provider’s server.
Annex B Mode
If you connect the Annex B model of the NetScreen-5GT Wireless ADSL device to a
Deutsch Telecom ADSL line, then you must configure the physical interfa ce on the ADSL
port for operation with this equipment. To do this:
22 User’s Guide
ADSL Configuration
WebUI
Network > Interfaces > Edit (for the adsl1 interface): Select DT for the Annex B
Mode, and then click Apply.
CLI
set interface adsl1 phy annex-b-mode dt
save
You do not need to configure this setting if you are using the Annex A model of the device
or if you are connecting the device to non-Deutsch Telecom equipment.
Static IP Address and Netmask
If your ISP gave you a specific, fixed IP address and netmask for your network, then
configure the IP address and netmask for the network and the IP address of the router
port connected to the NetScreen device. You need to also specify that the device use the
static IP address. (By default, the NetScreen device acts as a PPPoE or PPPoA client and
receives an IP address for the ADSL interface through negotiations with the PPPoE or
PPPoA server.)
To configure the static IP address 1.1.1.1/24 for the network:
WebUI
Network > Interfaces > Edit (for the adsl1 interface): Enter the following, and
then click Apply:
IP Address/Netmask: 1.1.1.1/24
Static IP: (select)
Note: You need to configure a PPPoE or PPPoA instance and bind it to the adsl1
interface, as described in the previous section. Make sure that you select “Obtain IP
using PPPoE” or “Obtain IP using PPPoA” and the name of the PPPoE or PPPoA
instance.
CLI
set interface adsl1 ip 1.1.1.1/24
set pppoe name poe1 static-ip
save
or
set interface adsl1 ip 1.1.1.1/24
set pppoa name poa1 static-ip
save
NetScreen-5GT Wireless 23
Chapter 2 Configuring the Device
To use Domain Name System (DNS) for domain name and address resolution, the
computers in your network need to have the IP address of at least one DNS server. If the
NetScreen device receives an IP address for the ADSL interface through PPPoE or
PPPoA, then it also automatically receives IP addresses for the DNS server(s). If the
computers in your network obtain their IP addresses from the DHCP server on the
NetScreen device, then the computers also obtain these DNS server address(es).
If you assign a static IP address to the ADSL interface, then the service provider must
give you the IP address(es) of the DNS server(s). You can either configure the DNS server
address on each computer in your network or configure the DHCP server on the Trust
zone interface so that it provides the DNS server address to each computer.
To configure the DHCP server on the Trust interface to provide the DNS server address
1.1.1.152 to computers in your network:
WebUI
Network > DHCP > Edit (for the Trust interface) > DHCP Server: Enter
1.1.1.152 for DNS1, and then click Apply.
CLI
set interface trust dhcp server option dns1 1.1.1.152
save
OPTIONAL CONFIGURATION
This section describes the following features on the NetScreen-5GT Wireless devices that
you may want to configure:
• Restricting Management
• Configuring Additional Policies
• Operational Mode
• Changing the Port Mode
• Configuring a Backup Untrust Zone Interface
• Changing the Trust Interface Address
Note: Not all of the optional configurations are described in detail in this manual. Refer
to the appropriate chapters in the NetScreen Concepts & Examples ScreenOS Reference
Guide for ScreenOS 5.0.0 for more information.
24 User’s Guide
Optional Configuration
Restricting Management
By default, anyone in your network can manage the NetScreen device if they know the
login and password. You can configure the NetScreen device to be managed only from one
or more specific hosts on your network. (And you can choose which services — for
example, WebUI, Telnet, ping — you want enabled on the NetScreen device.) Refer to the
“Administration” chapter in the “Administration” volume of the NetScreen Concepts &
Examples ScreenOS Reference Guide for ScreenOS 5.0.0.
Configuring Additional Policies
The NetScreen-5GT Wireless devices are configured with a default policy that permits
workstations in the Trust zone of your network to access any kind of service with outside
computers, while outside computers are not allowed to access or start sessions with your
workstations. You can configure policies that direct the NetScreen device to permit
outside computers to start specific kinds of sessions with your computers. To create or
modify policies, refer to the “Policies” chapter in the “Fundamentals” volume of the
NetScreen Concepts & Examples ScreenOS Reference Guide for ScreenOS 5.0.0.
Operational Mode
The operational mode is the way an interface on a NetScreen device processes traffic
between zones. By default, the NetScreen-5GT Wireless devices operates in Route mode
with network address translation (NAT) enabled on the Trust interface. This means that
when devices in the Trust zone send traffic to the Internet, the NetScreen device replaces
the original source IP addresses with the IP address of the Untrust interface. While the
NetScreen device assigns “private” IP addresses to the devices in your network, these
addresses remain hidden to computers outside your network.
If all devices in your network have public IP addresses, then you can configure the
NetScreen device for Route mode without NAT enabled. In Route mode without NAT
enabled, the NetScreen device routes traffic by checking IP addresses. For more
information about configuring the device for Route mode without NAT enabled, refer to
the “Interface Modes” chapter in the “Fundamentals” volume of the NetScreen Concepts &
Examples ScreenOS Reference Guide for ScreenOS 5.0.0.

NetScreen-5GT Wireless 27
Chapter 2 Configuring the Device
Configuring a Backup Untrust Zone Interface
By default, on NetScreen-5GT Wireless ADSL device, the adsl1 interface is the primary
connection to an outside network. Each port mode available on the NetScreen-5GT
Wireless ADSL device allows you the option of connecting either the Untrusted Ethernet
port or the Modem port as a backup connection to the outside network (see “Changing the
Port Mode” on page 26). You must bind the backup interface to the Untrust zone and
configure the interface appropriately.
Note: You can configure only one backup interface, using either the Untrusted Ethernet
port or Modem port connection. If you use the Untrusted port for the backup connection,
then configure the Untrust interface in Trust-Untrust port mode or the ethernet3 interface
for other port modes. If you use the Modem port for the backup connection, then configure
the serial interface for all port modes.
For example, to bind the Untrust interface to the Untrust zone:
WebUI
Network > Interfaces > Edit (for the untrust interface): Select Untrust from the
Zone Name drop-down list, and then click OK.
CLI
set interface untrust zone untrust
save
You also need to set a static IP address for the Untrust interface, or specify whether the
IP address for the interface is obtained via either DHCP or PPPoE. See the “Interfaces”
chapter in the “Fundamentals” volume of the NetScreen Concepts & Examples ScreenOS
Reference Guide for ScreenOS 5.0.0 for more information about configuring interface
parameters.
When the adsl1 interface and either the Ethernet interface (named untrust or ethernet3,
depending upon the port mode) or the serial interface is bound to the Untrust zone,
interface failover is automatically configured. That is, if the adsl1 interface becomes
unavailable, the NetScreen device automatically sends traffic to the ba ckup interface. The
device automatically sends traffic to the adsl1 interface when the adsl1 interface is again
available.
Note: Only the adsl1 interface is affected by failover. That is, if you have also configured
ADSL subinterfaces, the subinterfaces do not fail over to the backup interface.
You can also manually force failover and failback on the adsl1 interface. For more
information, see the “Interface Redundancy” chapter in the “High Availability” volume of
the NetScreen Concepts & Examples ScreenOS Reference Guide for ScreenOS 5.0.0.
28 User’s Guide
Verifying External Connectivity
Changing the Trust Interface Address
You can change the IP address and netmask of the Trust and wireless interfaces if
necessary. (Remember that when the Trust interface is in NAT mode, the IP addresses of
devices in your network are never seen by computers outside your network; outside
computers see only the IP address of the Untrust interface.) For example, you might need
to change the Trust interface to match the IP addresses that already exist on your
network. If you change the IP address and netmask of the Trust interface, then you also
need to change either the range of addresses that the NetScreen device assigns via DHCP
to devices in the network or disable the DHCP server on the Trust interface.
If the computers in your network obtain their IP addresses from the DHCP server on the
NetScreen device, then the computers also obtain their default gateway from the
NetScreen device. If a computer has a statically assigned IP address, then you must
manually set its default gateway to the IP address of the Trust interface on the NetScreen
device.
To assign a different IP address and netmask to the Trust interface, refer to the
“Interfaces” chapter in the “Fundamentals” volume of the NetScreen Concepts & Examples
ScreenOS Reference Guide for ScreenOS 5.0.0.
To change the DHCP settings for the NetScreen device, refer to the “System Parameters”
chapter in the “Fundamentals” volume of the NetScreen Concepts & Examples ScreenOS
Reference Guide for ScreenOS 5.0.0.
VERIFYING EXTERNAL CONNECTIVITY
To verify that workstations in your network can access resources on the Internet, start a
Web browser from any workstation in the network and enter the following URL:

RESETTING THE DEVICE TO FACTORY DEFAULTS
If you lose the admin password, you can reset the NetScreen device to its default settings.
This destroys any existing configurations, but restores access to the device.
Warning: Resetting the device deletes all existing configuration settings and renders
existing firewall and VPN service inoperative.
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 NetScreen Concepts & Examples
ScreenOS Reference Guide for ScreenOS 5.0.0.
• Using the reset pinhole on the rear panel of the devi ce, as des crib ed in the ne xt
section.
NetScreen-5GT Wireless 29
Chapter 2 Configuring the Device
Using 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 t o either view the device status LEDs on the
front panel or have a Console session as described in “Using a Console Connection” on
page 15.
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 amber. 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.
Reset Pinhole
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 confirmation. The Status LED lights
amber 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 turns amber 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 now blinks green.
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.
