Congratulations on your purchase of the Barricade™ Wireless
Broadband Router. SMC is proud to provide you with a powerful
yet simple communication device for connecting your local area
network (wired or wireless LAN) to the Internet. For those who
want to surf on the Internet at the lowest possible cost, this
Broadband Router provides a convenient and powerful solution.

About the Barricade

The Barricade provides Internet access to multiple users by sharing
a single-user account. The Barricade’s most outstanding features
include wireless LAN connectivity, as well as the
interface which allows you to connect to an xDSL or Cable
ISDN TA or PSTN analog modem. The
firewall protection and Virtual Private Network (VPN) services. It
also provides print services for any client attached to a LAN port.

Barricade

dual-port WAN

modem,

extensive

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

EATURES AND BENEFITS

Features and Benefits

• Internet connection to xDSL or Cable modem via 10 Mbps WAN

port

• Internet connection to ISDN TA or PSTN modem via RS232

console port

• Local network connection via 10/100 Mbps Ethernet ports or

11 Mbps wireless interface (supporting up to 20 mobile users)

• Print services for any client attached to the LAN

• DHCP for dynamic IP configuration, and DNS for domain name

mapping

• Firewall with client privileges, hacker prevention, 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)

• Virtual Private Network using PPTP, L2TP or IPSec

• User-definable application sensing tunnel supports applications

requiring multiple connections

• Supports CHAP authentication protocol for dial-up

identification

• Supports PPP dial-in connection using standard dial-up

program

• 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 Barricade, such as:

•Flexible LAN Access

The 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.

• 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
Barricade includes a built-in client for this protocol,
eliminating the need to install this service on your computer.

• Shared IP Address

The 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.

I

NTRODUCTION

• Virtual Server

If you have a fixed IP address, you can set up the 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 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.

1-3

A

PPLICATIONS

• User-Definable Application Sensing Tunnel

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

• DMZ Host Support

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 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
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.

• Virtual Private Network

The 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 Barricade are briefly
described below.

1-4

I

NTRODUCTION

• 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.

covered by a limited lifetime warranty.

Description of Hardware

The Barricade Wireless Broadband Router can be connected to the
Internet or to a remote site using its RJ-45 WAN port or RS232
console 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. It can even function as a print server.

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. 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 Barricade, data passing between devices
connected to your local area network can run up to 100 Mbps over
the Fast Ethernet ports.

The 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 on
the front panel; as well as one RJ-45 WAN port, one RS-232 serial
port, one parallel printer port, and two antennas on the rear panel.

address from your service provider.

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

The 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 Barricade away from any heating devices.

• Do not place the 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 Barricade.

Basic Installation Procedure

1. Connect the LAN: You can connect the Barricade to your PC,
or to a hub or switch. Run Ethernet cable
ports on the rear of the Barricade to
adapter or to another network device.

You can also connect the Barricade to your PC or to a wireless
access point via radio signals. Twist both antennas on the back
of the 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.

Attach to Your Network Using Ethernet Cabling

The three LAN ports on the 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 cable wiring
(auto-MDI/MDI-X) that allows you to use either straight-through
cable for connecting the gateway 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 Barricade to an Ethernet adapter on your PC. Otherwise, you
can cascade any of LAN ports on the 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 gateway. 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).

Attach to Your Network Using Radio Signals

Install a wireless network adapter in each computer that will be
connected to the Internet or your local network via radio signals.
SMC currently offers several wireless network cards, including the
SMC2602W PCI card and the SMC2652W PC card.

Rotate both antennas on the back of the Barricade to an upright
position. Try to place the Barricade in a position that is located in
the center of your wireless network. Normally, the higher you
place the antenna, the better the performance. Ensure that the
Barricade’s location provides optimal reception throughout your
home or office.

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 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 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 signals through the Barricade.

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