FEDERAL COMMUNICATION COMMISSION INTERFERENCE STATEMENT

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

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Description of Capabilities

| 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.

◆ RJ-45 Category 5 network cable

◆ AC power adapter

◆ Quick Installation Guide

◆ EZ Installation & Documentation CD

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.

ORTS

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.
