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.

NSTALLATION

• 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

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.

Encryption

If you are transmitting sensitive data across wireless channels, you
should enable encryption. Encryption requires you to use the same
set of encryption/decryption keys for the Wireless Barricade and

be aware that the extra processing time required for encryption
may affect the throughput for wireless communications.

4-14

C

ONFIGURING THE BARRICADE

You can automatically generate encryption keys or you can
manually enter the keys. For automatic 64-bit security, you enter a
passphrase that is used to create four keys (as shown below). The
automatic 128-bit security generates a single key by entering a
passphrase. To manually configure the keys, enter five
hexadecimal pairs for each 64-bit key, or enter 13 pairs for the
single 128-bit key. (A hexadecimal digit is a number or letter in the
range 0-9 or A-F.)

If you use encryption, then configure the same keys used for the
Wireless Barricade on each of your wireless clients. Note that the
Wired Equivalent Privacy (WEP) protects data transmitted between
wireless nodes, but does not protect any transmissions over your
wired network or over the Internet.

ETWORKING AND CLIENT SERVICES

Configuring Client Services

The Wireless Barricade includes a broad range of client services,
including firewall protection, network address translation, virtual
server, connection support for special applications, and restricted
Internet access for specified clients. You can configure these
functions using the Setup Wizard by clicking “Enter” at the bottom
of the Advanced Settings screen, or by selecting specific items
from the menu on the left of the screen.

Firewall Protection

The Wireless Barricade’s firewall can 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. The firewall does not
significantly affect system performance, so we advise leaving it
enabled to protect your network users.

ONFIGURING THE BARRICADE

Virtual Server

If you configure the Wireless Barricade as a virtual server, remote
users accessing services such as Web or FTP at your local site via
public IP addresses can be automatically redirected to local servers
configured with private IP addresses. In other words, depending
on the requested service (TCP/UDP port number), the Wireless
Barricade redirects the external service request to the appropriate
server (located at another internal IP address).

The WAN interface must have a fixed IP address to utilize this
function. For example, if you set Type/Public Port to TCP/80
(HTTP or Web) and the Private IP/Port to 192.168.2.2/80, then all

4-17

N

ETWORKING AND CLIENT SERVICES

HTTP request from outside users will be transferred to 192.168.2.2.
Therefore, by just entering the IP Address provided by the ISP,
Internet users can access the service they need at the local address
to which you redirect them.

Some of the more common TCP service ports include:

HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.

Enabling Special Applications

Some applications require multiple connections, such as Internet
gaming, videoconferencing, Internet telephony and others. These
applications cannot work with Network Address Translation (NAT)
enabled. If you need to run applications that require multiple
connections, use the following screen to specify the additional
public ports to be opened for each application.

C

ONFIGURING THE BARRICADE

Specify the port normally associated with an application in the
“Trigger Port” field, select the protocol type as TCP or UDP, then
enter the public ports associated with the trigger port to open
them for inbound traffic.

Note: If an application still cannot function correctly after

enabling multiple ports via the Special Application screen,
you may have to open the client PC for full Internet access
using the DMZ Host option on the “Misc” screen.

Client Filtering

You can filter Internet access for local clients based on IP address,
application type (i.e., HTTP port), and time of day.

For example, this screen shows that clients in the address range

192.168.2.50-99 are permanently restricted from using FTP (Port

21), while clients in the address range 192.168.2.110-119 are
blocked from browsing the Internet from Monday through Friday.

ETWORKING AND CLIENT SERVICES

MAC Filtering

You can filter Internet access for local wired and wireless clients
based on MAC address.

MAC Address Control: Every client that connects to the network
has a unique MAC (Media Access Control) address on his or her
Ethernet adapter. An administrator can have more control—and
more security—over the network by specifying which MAC
addresses are allowed to access the Wireless Barricade. You can
enable this feature by checking the “Enabled” box.

Connection Control: Connection control allows an administrator
to allow or deny clients access to the Wireless Barricade and the
Internet. Check “Connection control” to control which of the wired
AND wireless clients will be able to “connect” to the Wireless
Barricade and to the Internet. If a client is denied “connection” to
this device, it means that the client can’t access the Internet and
some network resources. Choose “Allow” or “Deny” to allow or
deny clients whose MAC addresses are not listed in the “Control
table.”

4-20

C

ONFIGURING THE BARRICADE

When a wired client is allowed to “Connect” to the Wireless
Barricade, it means that it has full access to the Internet and
network resources.

When a wired client is not allowed to “Connect” to the Wireless
Barricade, it means that it CAN communicate with the other clients
on the wired LAN, but CANNOT:

• Connect to the Internet

• Use the Print Server function

• Communicate with the clients on the wireless LAN

• Use the Wireless Barricade’s Web configuration

Association Control: The Association process is the exchange of
information between wireless clients and a wireless access point to
establish a link between them. A wireless client is capable of
transmitting and receiving data to an access point only after the
association process is sucessfully completed.

Association control allows an administrator to allow or deny
wireless clients from linking to the Wireless Barricade. Check
“Association control” to control which of the wireless clients will
be able to “associate” to the wireless LAN. If a client is denied
“association” to the wireless LAN, it means that the client can’t
send or receive any data through the Wireless Barricade. Choose

you can use the Ping command to check if your computer is
successfully connected to the Wireless Barricade. The following
example shows how the Ping procedure can be executed in an
MS-DOS window. First, execute the Ping command:

ping 192.168.2.1

If the following messages appear:

Pinging 192.168.2.1 with 32 bytes of data:
Reply from 192.168.2.1: bytes=32 time=2ms TTL=64

a communication link between your computer and the Wireless
Barricade has been successfully established.

Otherwise, if you get the following messages,

Pinging 192.168.2.1 with 32 bytes of data:
Request timed out.

there may be something wrong in your installation procedure.
Check the following items in sequence:

1. Is the Ethernet cable correctly connected between the Wireless
Barricade and your computer?

The LAN LED on the Wireless Barricade and the Link LED of
the network card on your computer must be on.

2. Is TCP/IP properly configured on your computer?

If the IP address of the Wireless Barricade is 192.168.2.1, the IP
address of your PC must be from 192.168.2.2 - 192.168.2.254
and the default gateway must be 192.168.2.1.

Troubleshooting Chart

Symptom Action

LED Indicators

Power LED is Off • External power supply has failed or is

disconnected.

• Check connections between the Wireless
Barricade, the external power supply, and the
wall outlet.

• If the power indicator does not turn on when the
power cord is plugged in, you may have a
problem with the power outlet, power cord, or
external power supply.

However, if the unit powers off after running for
a while, check for loose power connections,
power losses or surges at the power outlet.

If you still cannot isolate the problem, then the
external power supply may be defective. In this

Twisted-pair Cable

Caution: DO-NOT plug a phone jack connector into any RJ-45

port. Use only twisted-pair cables with RJ-45 connectors
that conform with FCC standards.

For 10BASE-T/100BASE-TX connections, a twisted-pair cable
must have two pairs of wires. Each wire pair is identified by two
different colors. For example, one wire might be red and the other,
red with white stripes. Also, an RJ-45 connector must be attached
to both ends of the cable. All RJ-45 ports on the Wireless Barricade,
except for the WAN port, support automatic MDI/MDI-X
configuration. This means that you can use straight-through cable
to attach the LAN ports to any network device. However, when
connecting the WAN port to a broadband modem, you will need to
use either straight-through or crossover cable, depending on the
port type used on the modem.
