EATURES AND BENEFITS
Features and Benefits
• Internet connection to xDSL or cable modem via a 10/100 Mbps
WAN port
• Local network connection via 10/100 Mbps Ethernet ports or
11 Mbps wireless interface (supporting up to 128 mobile users)
• 802.11b Compliant – interoperable with multiple vendors
• Provides seamless roaming within 802.11b WLAN environment
• Supports 64-bit and 128-bit WEP (Wired Equivalent Privacy)
• DHCP for dynamic IP configuration, and DNS for domain name
mapping
• Firewall with Stateful Packet Inspection, client privileges, intrusion
detection, VPN, and NAT
• NAT also enables multi-user access with a single-user account,
and virtual server functionality (providing protected access to
Internet services such as Web, FTP, mail and Telnet)
• Supports VPN (Virtual Private Network) tunneling, IPSec and PPTP
• Easy setup through a Web browser on any operating system
that supports TCP/IP
• Compatible with all popular Internet applications
1-2
Applications
Many advanced applications are provided by the Wireless Barricade Plus,
such as:
• Flexible LAN Access
The Wireless Barricade Plus 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.
• Internet Access
This device supports Internet access through an xDSL, or Cable
connection. Since many DSL providers use PPPoE to establish
communications with end users, the Wireless Barricade Plus includes
a built-in client for this protocol, eliminating the need to install this
service on your computer.
• Shared IP Address
I
NTRODUCTION
The Wireless Barricade Plus 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
Plus to act as a virtual host using network address translation (NAT).
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 Plus 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.
• DMZ Host Support
Allows a networked computer to be fully exposed to the
Internet.
• Security
The Wireless Barricade Plus 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 Plus’ 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.
• Stateful Packet Inspection (SPI)
Stateful Packet Inspection is one of the firewall features provided
by the Wireless Barricade Plus. The SPI ensures that the data coming
into your network was requested by an end node computer on your
network. The Wireless Barricade Plus examines the incoming data and
compares it to a database of trusted information. As traffic leaves
the network, it is defined by certain characteristics. Incoming
information is then compared to these sets of characteristics. If
the incoming data matches the predefined set of characteristics,
1-4
I
NTRODUCTION
the incoming traffic is allowed. If no match is found, the
incoming traffic is discarded.
• Virtual Private Network (VPN)
The Wireless Barricade Plus supports two of the most commonly
used VPN protocols – PPTP 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 Plus are briefly described below.
• Point-to-Point Tunneling Protocol (PPTP) – 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.
• IP Security (IPSec) – Provides IP network-layer encryption. IPSec
can support large encryption networks (such as the Internet) by
using digital certificates for device authentication.

• 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 10/100 Mbps, full duplex. This port only
supports MDI-X pin signals, so you will have to use either
straight- through or crossover cable depending on the port type
used on the modem.
• Two detachable antennas (dipole, omni-directional).

Basic Installation Procedure
1. Connect the LAN: You can connect the Wireless Barricade Plus to
your PC, or to a hub or switch. Run Ethernet cable
LAN ports on the rear of the Wireless Barricade Plus to
computer’s
network adapter or to another network device.
You can also connect the Wireless Barricade Plus to your PC (using a
wireless client adapter) via radio signals. Position both antennas
on the back of the Wireless Barricade Plus 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.)
2. Connect the WAN: Prepare an Ethernet cable for connecting the
Wireless Barricade Plus to a cable/xDSL modem or Ethernet router.
3. Power on: Connect the power adapter to the Wireless Barricade Plus.

The three LAN ports on the Wireless Barricade Plus 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 Plus 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 Plus to an Ethernet adapter on your PC. Otherwise,
you can cascade any of LAN ports on the Wireless Barricade Plus 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 Plus. Instead, use only
twisted-pair cables with RJ-45 connectors that conform
with FCC standards.

ETWORKING AND CLIENT SERVICES
If you configure the Wireless Barricade Plus 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 Plus 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
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.

The Intrusion Detection feature of the Wireless Barricade Plus limits the
access of the incoming traffic from the WAN port. When the SPI feature
is turned on, all the incoming packets will be blocked unless certain types
of traffic types are checked by the users. When the user checkes certain
types of traffic, only the particular type of traffic initiated from the Internal
LAN will be allowed. For example, if the user only checks “FTP service”
from the Stateful Packet Inspection heading, all the incoming traffic will be
blocked except the FTP connection initiated from the local LAN.
• Stateful Packet Inspection
This option allows you to select different application types that are using
dynamic port numbers. If you need to use the Stateful Packet Inspection
(SPI) for blocking packets, check the radio button in the “Enable SPI and
Anti-DoS firewall protection” field and then check the inspection type that
you need, such as Packet Fragmentation, TCP Connection, UDP Session,
FTP Service, H.323 Service and TFTP Service.
• Hacker Prevention Feature
The Wireless Barricade Plus’ firewall inspects packets at the application
layer, and maintains TCP and UDP session information, including
timeouts and number of active sessions, provides the ability to detect and
prevent certain types of network attacks such as DoS attacks.
Network attacks that deny access to a network device are called
denial-of-service (DoS) attacks. Denials of Service (DoS) attacks are aimed
at devices and networks with a connection to the Internet. Their goal is
not to steal information, but to disable a device or network so users no
longer have access to network resource.

(Teardrop Attack), Brute-force attack, Land Attack, IP Spoofing attack, IP
with zero length, TCP null scan (Port Scan Attack), UDP port loopback,
Snork Attack etc..
Note: The firewall does not significantly affect system performance, so
we advise enabling the prevention features to protect your network
users.

Configuring Your Computer with Windows 95/98/ME
You may find that the instructions here do not exactly match your
version of Windows. This is because these steps and screenshots were
created from Windows 98. Windows 95 and Windows Millennium
Edition are very similar, but not identical, to Windows 98.
Step 1. Configure TCP/IP Settings
After you have completed the hardware setup by connecting your devices,
you need to configure your computer to connect to your Wireless
Barricade Plus. You need to determine how your ISP issues your IP
address. Many ISPs issue these numbers automatically using a
networking technology known as Dynamic Host Configuration
Protocol, or DHCP. Other ISPs will specify your IP address and
associated numbers, which you must enter manually. This is also
known as a static IP address. How your ISP assigns your IP address
determines how you will configure your computer.
1. From the Windows
desktop, click the "Start"
button. Choose "Settings,"
then click "Control Panel."
