I NTRODUCTION
1-3
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
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.

A PPLICATIONS
1-4
•VirtualServer
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,

I NTRODUCTION
1-5
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.

Description of Hardware
The Wireless Barricade Plus can be connected to the Internet or to a
remote site using its RJ-45 WAN port. It can be connected directly to your
PC or to a local area network using any of the three Fast Ethernet
LAN ports or
through the wireless interface.
Access speed to the Internet depends on your service type.
Full-rate ADSL can provide up to 8 Mbps downstream and 640
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. 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 Plus, data passing between
devices connected to your local area network can run up to
100 Mbps over the Fast Ethernet ports.
The Wireless Barricade Plus 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, as well as two detachable antennas
on the rear panel.

I NSTALLATION

• Three RJ-45 ports for connection to a 10BASE-T/100BASE-TX
Ethernet Local Area Network (LAN). These ports can auto-
negotiate 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).
