This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communications. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one of the following
measures:
◆ Reorient or relocate the receiving antenna
◆ Increase the separation between the equipment and receiver
◆ Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected
◆ Consult the dealer or an experienced radio/TV technician for help

1 INTRODUCTION
The Barricade Wireless Broadband Router (SMCWBR14S-N4) supports
routing from an Internet Service Provider (ISP) connection (DSL or cable
modem) to a local network. It is simple to configure and can be up and
running in minutes.
KEY HARDWARE FEATURES
The following table describes the main hardware features of the Gateway
Router.

| Introduction
APPLICATIONS Many advanced networking features are provided by the Barricade:
◆ Easy setup through a Web browser on any operating system that
supports TCP/IP.
◆ Compatible with all popular Internet applications.
In addition, the Gateway Router offers full network management
capabilities through an easy-to-configure web interface.
◆ Wired LAN — The Barricade provides connectivity to wired
10/100 Mbps devices, making it easy to create a network in small
offices or homes.
◆ Internet Access — This device supports Internet access through a
WAN connection. Since many DSL providers use PPPoE to establish
communications with end users, the Barricade includes built-in clients
for these protocols, eliminating the need to install these services on
your computer.
◆ Shared IP Address — The Barricade provides Internet access for up
to 253 users via a single shared IP address. Using only one ISP
account, multiple users on your network can browse the Web at the
same time.
◆ Virtual Server — If you have a fixed IP address, you can set 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.
◆ DMZ Host Support — Allows a networked computer to be fully
exposed to the Internet. This function is used when NAT and firewall
security prevent an Internet application from functioning correctly.
◆ Security — The Barricade supports security features that deny
Internet access to specified users, or filter all requests for specific
services the administrator does not want to serve. WPA (Wi-Fi
Protected Access) and MAC filtering provide security over the wireless
network.
◆ Virtual Private Network (VPN) — The Barricade supports one of the
most commonly used VPN protocols – PPTP. This protocol allows remote
users to establish a secure connection to their corporate network. If
your service provider supports VPNs, then 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.

◆ 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.

◆ Barricade Wireless Broadband Router
◆ RJ-45 Category 5 network cable
◆ AC power adapter

HARDWARE DESCRIPTION
The Barricade Wireless Broadband Router, from herein refered to as
Gateway Router, connects to the Internet using its RJ-45 WAN port. It
connects directly to your PC or to a local area network using its RJ-45 Fast
Ethernet LAN ports.
The Gateway Router includes an LED display on the front panel for system
power and port indications that simplifies installation and network
troubleshooting.

The Wireless Broadband Router has four 100BASE-TX RJ-45 ports that can
be attached directly to 10BASE-T/100BASE-TX LAN segments.
These port support automatic MDI/MDI-X operation, so you can use
straight-through cables for all network connections to PCs, switches, or
hubs.
POWER CONNECTOR The Wireless Broadband Router must be powered with its supplied power
adapter. Failure to do so results in voiding of any warrantly supplied with
the product. The power adapter automatically adjusts to any voltage
between 100~240 volts at 50 or 60 Hz, and supplies 5 volts DC power to
the unit. No voltage range settings are required.

2 NETWORK PLANNING
The Wireless Broadband Router is designed to be very flexible in its
deployment options. It can be used as an Internet gateway for a small
network, or as an access point to extend an existing wired network to
support wireless users. It also supports use as a wireless bridge to connect
up to four wired LANs.
This chapter explains some of the basic features of the Wireless Broadband
Router and shows some network topology examples in which the device is
implemented.
INTERNET GATEWAY ROUTER
The Wireless Broadband Router can connect directly to a cable or DSL
modem to provide an Internet connection for multiple users through a
single service provider account. Users connect to the Wireless Broadband
Router either through a wired connection to a LAN port, or though the
device’s own wireless network. The Wireless Broadband Router functions as
an Internet gateway when set to Gateway Mode.
An Internet gateway employs several functions that essentially create two
separate Internet Protocol (IP) subnetworks; a private internal network
with wired and wireless users, and a public external network that connects
to the Internet. Network traffic is forwarded, or routed, between the two
subnetworks.

LAN Access Point
Figure 4: Operating as an Internet Gateway Router
LAN ACCESS POINT
The private local network, connected to the LAN port or wireless interface,
provides a Dynamic Host Configuration Protocol (DHCP) server for
allocating IP addresses to local PCs and wireless clients, and Network
Address Translation (NAT) for mapping the multiple "internal" IP addresses
to one "external" IP address.
The public external network, connected to the WAN port, supports DHCP
client, Point-to-Point Protocol over Ethernet (PPPoE) and static IP for
connection to an Internet service provider (ISP) through a cable or DSL
modem.
The Wireless Broadband Router can provide an access point service for an
existing wired LAN, creating a wireless extension to the local network. The
Wireless Broadband Router functions as purely an access point when set to
Bridge Mode. When used in this mode, there are no gateway functions
between the WAN port and the LAN and wireless interface.
A Wi-Fi wireless network is defined by its Service Set Identifier (SSID) or
network name. Wireless clients that want to connect to a network must set
their SSID to the same SSID of the network service.
