1-1CHAPTER 1INTRODUCTIONCongratulations on your purchase of the Barricade Wireless Broadband Router with built-in ADSL Modem (SMC7404WBRA). We are proud to provide you with a powerful yet simple communication device for connecting your local area network (LAN) to the Internet. For those who want to surf the Internet in the most secure way, this Router provides a convenient and powerful solution. About the BarricadeThe Barricade provides Internet access to multiple users by sharing a single-user account. Support is provided for both wired and wireless devices. New technology provides wireless security via WEP (Wired Equivalent Privacy) encryption and MAC address filtering. It is simple to configure and can be up and running in minutes. Features• Internet connection via an RJ-11 WAN port.• Local network connection via four 10/100 Mbps Ethernet ports.• On-board IEEE 802.11b 11 Mbps wireless network adapter.• DHCP for dynamic IP configuration, and DNS for domain name mapping.• Firewall with Stateful Packet Inspection, client privileges, intrusion detection, and NAT.

INTRODUCTION1-2• NAT also enables multi-user Internet access via a single user account, and virtual server functionality (providing protected access to Internet services such as Web, FTP, e-mail, and Telnet).• VPN pass-through (IPSec-ESP Tunnel mode, L2TP, PPTP).• User-definable application sensing tunnel supports applications requiring multiple connections.• Easy setup through a Web browser on any operating system that supports TCP/IP.• Compatible with all popular Internet applications. ApplicationsMany advanced networking features are provided by the Barricade:•Wireless and Wired LANThe Barricade provides connectivity to wired 10/100 Mbps devices, and wireless IEEE 802.11b compatible devices, making it easy to create a network in small offices or homes.•Internet AccessThis device supports Internet access through an ADSL connection. Since many ADSL providers use PPPoE or PPPoA 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 AddressThe 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.

APPLICATIONS1-3•Virtual ServerIf 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 SupportAllows 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 that administrator does not want to serve. The Barricade’s firewall also blocks 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. WEP (Wired Equivalent Privacy), SSID, and MAC filtering provide security over the wireless network.

INTRODUCTION1-4•Virtual Private Network (VPN) 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 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.• L2TP merges the best features of PPTP and L2F – Like PPTP, L2TP requires that the ISP’s routers support the protocol. • IP Security – Provides IP network-layer encryption. IPSec can support large encryption networks (such as the Internet) by using digital certificates for device authentication.

HARDWARE DESCRIPTION2-3Hardware Description The Barricade contains an integrated ADSL modem and connects to the Internet or to a remote site using its RJ-11 WAN port. It connects directly to your PC or to a local area network using any of the four RJ-45 Fast Ethernet LAN ports or via a wireless network adapter.Access speed to the Internet depends on your service type. Full-rate ADSL provides up to 8 Mbps downstream and 640 Kbps upstream. G.lite (or splitterless) ADSL provides up to 1.5 Mbps downstream and 512 Kbps upstream. However, you should note that the actual rate provided by specific service providers may vary dramatically from these upper limits.Data passing between devices connected to your local area network can run at up to 100 Mbps over the Fast Ethernet ports and 11 Mbps over the built-in wireless network adapter.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 the following ports on the rear panel:Item DescriptionLAN PortsFast Ethernet ports (RJ-45). Connect devices on your local area network to these ports (i.e., a PC, hub, or switch).Parallel Printer PortOne parallel printer port that can be connected to a printer. This printer can then be shared by all LAN users.Reset ButtonUse this button to reset the power and restore the default factory settings. To reset without losing configuration settings, see “Reset” on page 4-55.Power InletConnect the included power adapter to this inlet.Warning: Using the wrong type of power adapter may cause damage.WAN PortWAN port (RJ-11).

ISP SETTINGS2-5ISP SettingsPlease collect the following information from your ISP before setting up the Barricade (for PPPoE, PPPoA or fixed IP users only):• For PPPoE and PPPoA users• An ISP account user name and password • ISP authentication type or script (if not PAP/CHAP)•For fixed IP users• IP address and subnet mask• IP address for your ISP’s Gateway Server and Domain Name ServerConnect the SystemThe 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.Connect the ADSL LineRun standard telephone cable from the wall jack providing ADSL service to the WAN port on your Barricade. When inserting an ADSL RJ-11 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. If you are using splitterless ADSL service, add low-pass filters between the ADSL wall jack and your telephones. (These filters pass voice

INSTALLATION2-6signals through but filter data signals out.) Phone Line ConfigurationInstalling a Full-rate ConnectionIf you are using a full-rate (G.dmt) connection, your service provider will attach the outside ADSL line to a data/voice splitter. In this case you can connect your phones and computer directly to the splitter as shown below:Figure 2-1.

INSTALLATION2-8Use twisted-pair cabling to connect any of the four LAN ports on the Barricade to an Ethernet adapter on your PC. Otherwise, cascade any of the 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 connector, be sure the tab on the connector clicks into position to ensure that it is properly seated. Warning:Do not plug a phone jack connector into an RJ-45 port. This may damage the Barricade. Notes: 1. Use 100-ohm shielded or unshielded twisted-pair cable with RJ-45 connectors for all Ethernet ports. 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 length does not exceed 100 meters (328 feet).Connect the Power AdapterPlug the power adapter into the power socket on the rear of the Barricade, and the other end into a power outlet. Check to confirm the power indicator on the front panel is lit. If the power indicator is not lit, refer to “Troubleshooting” on page A-1. In case of a power input failure, the Barricade will automatically restart and begin to operate once the input power is restored.If the Barricade is properly configured, it will take about 30 seconds to establish a connection with the ADSL service provider after powering up. During this time the Sync indicator will flash. After the ADSL connection has been established, the ADSL Sync LED will stay on.

3-1CHAPTER 3CONFIGURING CLIENT PCAfter completing hardware setup by connecting all your network devices, you need to configure your computer to connect to the Barricade. First determine how your ISP issues your IP address. Many ISPs issue these numbers automatically using Dynamic Host Configuration Protocol (DHCP). Other ISPs provide a static IP address and associated numbers, which you must enter manually. How your ISP assigns your IP address determines how you need to configure your computer. See this section for Windows 95/98/Me configuration. See “Windows NT 4.0” on page 3-8, “Windows 2000” on page 3-13, “Windows XP” on page 3-17, or “Configuring Your Macintosh Computer” on page 3-21 depending on your operating system.TCP/IP ConfigurationTo access the Internet through the Barricade, you must configure the network settings of the computers on your LAN to use the same IP subnet as the Barricade. The default network settings for the Barricade are:IP Address: 192.168.2.1 Subnet Mask: 255.255.255.0Note: These settings can be changed to fit your network requirements, but you must first configure at least one computer to access the Barricade’s Web configuration interface in order to make the required changes. (See “Configuring the Barricade” on page 4-1 for instruction on configuring the Barricade.)
