The Wireless Barricade supports dial-on-demand for ISDN/PSTN
service, automatically connecting to the Internet when there are
requests and terminating the connection if no further requests
occur. This dual-port design also supports fail-over Internet access
through the secondary WAN port (i.e., the serial port can be used
for primary or backup Internet access).

This new Wireless Barricade technology provides many
cost-effective functions and management benefits. It is simple to
configure and can be up and running in minutes.

Applications

Many advanced applications are provided by the Wireless Barricade,
such as:

•Flexible LAN Access

The Wireless Barricade provides connectivity to 10/100 Mbps
wired devices as well as 11 Mbps wireless mobile users. The
wireless interface makes it easy to create a network in
difficult-to-wire environments, or to provide quick access to
databases for mobile workers.

I

NTRODUCTION

• Internet Access

This device supports Internet access through an xDSL, Cable,
ISDN or PSTN connection. Since many DSL providers use
PPPoE to establish communications with end users, the
Wireless Barricade includes a built-in client for this protocol,
eliminating the need to install this service on your computer.

• Shared IP Address

The Wireless Barricade provides Internet access for up to 253
users with a shared IP address. Using only one ISP account,
multiple users on your network can browse the Web at the
same time.

1-3

A

PPLICATIONS

• Virtual Server

If you have a fixed IP address, you can set up the Wireless
Barricade to act as a virtual host for network address
translation. Remote users access various services at your site
using a constant IP address. Then, depending on the
requested service (or port number), the Wireless Barricade can
route the request to the appropriate server (at another internal
IP address). This secures your network from direct attack by
hackers, and provides more flexible management by allowing
you to change internal IP addresses without affecting outside
access to your network.

• User-Definable Application Sensing Tunnel

You can define special applications that require multiple
connections such as Internet gaming, videoconferencing, and
Internet telephony. The Wireless Barricade can then sense the
application type and open a multi-port tunnel for it.

• DMZ Host Support

1-4

Allows a networked computer to be fully exposed to the
Internet. This function is used when the special application
sensing tunnel feature is insufficient to allow an application to
function correctly.

• Security

The Wireless Barricade supports security features that can
deny Internet access to specified users, or filter all requests for
specific services the administrator does not want to serve. The
Wireless Barricade’s firewall can also block common hacker
attacks, including IP Spoofing, Land Attack, Ping of Death, IP
with zero length, Smurf Attack, UDP port loopback, Snork
Attack, TCP null scan, and TCP SYN flooding.

I

NTRODUCTION

• Virtual Private Network

The Wireless Barricade supports three of the most commonly
used VPN protocols – PPTP, L2TP and IPSec. These protocols
allow remote users to establish a secure connection to their
corporate network. If your service provider supports VPNs,
then any of these protocols can be used to create an
authenticated and encrypted tunnel for passing secure data
over the Internet (i.e., a traditionally shared data network).
The VPN protocols supported by the Wireless Barricade are
briefly described below.

• Point-to-Point Tunneling Protocol – Provides a secure

tunnel for remote client access to a PPTP security gateway.
PPTP includes provisions for call origination and flow
control required by ISPs.

• Layer Two Tunneling Protocol – Includes most of the

features provided by PPTP, but has less overhead and is
more suited for managed networks.

• IP Security – Provides IP network-layer encryption. IPSec

can support large encryption networks (such as the
Internet) by using digital certificates for device
authentication.

Mbps upstream. G.lite (or splitterless) ADSL provides up to 1.5
Mbps downstream and 512 Kbps upstream. Cable modems can
provide up to 36 Mbps downstream and 2 Mbps upstream. ISDN
can provide up to 128 Kbps when using two bearer channels. And
PSTN analog connections can now run up to 56 Kbps. However,
you should note that the actual rate provided by specific service
providers may vary dramatically from these upper limits.

Although access speed to the Internet is determined by the modem
type connected to your Wireless Barricade, data passing between
devices connected to your local area network can run up to
100 Mbps over the Fast Ethernet ports.

The Wireless Barricade includes an LED display on the front panel
for system power and port indications that simplifies installation
and network troubleshooting. It also provides three RJ-45 LAN
ports, one RJ-45 WAN port, one RS-232 serial port, one parallel
printer port, as well as two antennas on the rear panel.

• Three RJ-45 ports for connection to a 10BASE-T/100BASE-TX
Ethernet Local Area Network (LAN). These ports can auto­negotiate the operating speed to 10/100 Mbps, the mode to
half/full duplex, and the pin signals to MDI/MDI-X (i.e.,
allowing these ports to be connected to any network device
with straight-through cable). These ports can be connected
directly to a PC or to a server equipped with an Ethernet
network interface card, or to a networking device such as an
Ethernet hub or switch.

• One RJ-45 port for connection to an xDSL or Cable modem.
This port is fixed at 10 Mbps, full duplex. Use a Category 5
cable to connect this WAN port to a xDSL or Cable modem.

• One RS-232 seri a l port to connect to an ISDN T erminal Adap ter
(TA) or to a PSTN analog modem.

• One parallel printer port that can be connected to a printer.
This printer can then be shared by any LAN/WLAN users.

• Two antennas (dipole, omni-directional).

following minimum requirements:

• Internet access from your local telephone company or ISP
using an xDSL modem, Cable modem, ISDN TA, or PSTN
analog modem. You may also have access over the telephone
system to an analog modem at another site.

• A PC using a fixed IP address or dynamic IP address assignment
via DHCP, as well as a Gateway server address and DNS server
address from your service provider.

• For wired LAN connection, you need a computer equipped
with a 10 Mbps, 100 Mbps, or 10/100 Mbps Fast Ethernet card,
or a USB-to-Ethernet converter. For wireless LAN connections,
each computer must have an 11 Mbps wireless adapter.

Connect the System

The Wireless Barricade can be positioned at any convenient
location in your office or home. No special wiring or cooling
requirements are needed. You should, however comply with the
following guidelines:

• Keep the Wireless Barricade away from any heating devices.

• Do not place the Wireless Barricade in a dusty or wet

environment.

You should also remember to turn off the power, remove the
power cord from the outlet, and keep your hands dry when you
install the Wireless Barricade.

Basic Installation Procedure

1. Connect the LAN: You can connect the Wireless Barricade to

your PC, or to a hub or switch. Run Ethernet cable
the LAN ports on the rear of the Wireless Barricade to
computer’s

You can also connect the Wireless Barricade to your PC (using
a wireless client adapter) via radio signals. Position both
antennas on the back of the Wireless Barricade into the desired
positions. For more effective coverage, you may want to
position one antenna along the vertical axis and the other
antenna along the horizontal axis. (The antennas emit

signals along the toroidal plane – and thus provide more
effective coverage when positioned along alternate axes.)

The three LAN ports on the Wireless Barricade can auto-negotiate
the connection speed to 10 Mbps Ethernet or 100 Mbps Fast
Ethernet, as well as the transmission mode to half-duplex or
full-duplex. These LAN ports also support auto-configuration for
pin signals (auto-MDI/MDI-X) that allows you to use
straight-through cable for connecting the Wireless Barricade to any
network device. (See Appendix B for details on wiring.)

Use twisted-pair cable to connect any of the three LAN ports on
the Wireless Barricade to an Ethernet adapter on your PC.
Otherwise, you can cascade any of LAN ports on the Wireless
Barricade to an Ethernet hub or switch, and then connect your PC
or other network equipment to the hub or switch. When inserting
an RJ-45 plug, be sure the tab on the plug clicks into position to
ensure that it is properly seated.

Warning: Do not plug a phone jack connector into any RJ-45

port. This may damage the Wireless Barricade. Instead,
use only twisted-pair cables with RJ-45 connectors that
conform with FCC standards.

Notes: 1. Use 100-ohm shielded or unshielded twisted-pair cable

with RJ-45 connectors for all connections. Use Category
3, 4 or 5 for connections that operate at 10 Mbps, and
Category 5 for connections that operate at 100 Mbps.

2. Make sure each twisted-pair cable does not exceed 100
meters (328 feet).

Computers equipped with a wireless adapter can communicate
with each other as an independent wireless LAN by configuring
each computer to the same radio channel. However, the Wireless
Barricade can provide access to your wired/wireless LAN or to the
Internet for all wireless workstations. Each wireless PC in this
network infrastructure can talk to any computer in the wireless
group via a radio link, or access other computers or network
resources in the wired LAN infrastructure or over the Internet via
the Wireless Barricade.

The wireless infrastructure configuration not only extends the
accessibility of wireless PCs to the wired LAN, but also doubles the
effective wireless transmission range for wireless PCs by
retransmitting incoming radio signals through the Wireless
Barricade.

A wireless infrastructure can be used for access to a central
database, or for connection between mobile workers, as shown in
