Congratulations on your purchase of the Barricade™ Broadband Router. SMC is 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 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 most outstanding feature of the Barricade is the connect to an xDSL or Cable modem. The Virtual Private Network (VPN) services. It also provides print services for any client attached to a LAN port.

dual-port WAN interface which allows you to

modem, ISDN TA or PSTN analog

Barricade

provides

extensive firewall protection and

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.

1-1

EATURES AND BENEFITS

Features and Benefits

• Internet connection to xDSL or Cable modem via a 10/100 Mbps WAN port

• Internet connection to ISDN TA or PSTN modem via an RS-232 console port

• Local network connection via 10/100 Mbps Ethernet ports

• Built-in Print Server 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 support using PPTP, L2TP or IPSec pass-through

• User-definable application sensing tunnel supports applications requiring multiple connections

• Supports CHAP authentication protocol for dial-up identification

• Supports PPP dial-out connection

• 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:

• LAN Access

The Barricade provides connectivity to 10/100 Mbps devices, making it easy to create a network in small offices or homes.

• 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.

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

PPLICATIONS

• User-Definable Application Sensing Tunnel

You can define special applications that require multiple connections such as Internet gaming, videoconferencing, 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

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.

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 4 RJ-45 LAN ports on the front panel, as well as one RJ-45 WAN port, one RS-232 serial port and one parallel printer port on the rear panel:

NSTALLATION

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

• One RS-232 serial port to connect to an ISDN Terminal Adapter (TA) or to a PSTN analog modem.

• One parallel printer port that can be connected to a printer. This printer can then be shared by any LAN users.

Attach to Your Network Using Ethernet Cabling

The 4 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. The LAN ports on SMC7004ABR support auto-configuration for pin signals (auto-MDI/ MDI-X) that allows you to use straight-through cable for connecting the Barricade to any network device. (See Appendix B for details on wiring.)

Use twisted-pair cable to connect any of the 4 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 Barricade. 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.

Firewall Protection

The Barricade’s firewall can 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. The firewall does not significantly affect system performance, so we advise leaving it enabled to protect your network users.

Virtual Server

If you configure the Barricade as a virtual server, remote users accessing services such as Web or FTP at your local site via public IP addresses can be automatically redirected to local servers configured with private IP addresses. In other words, depending on the requested service (TCP/UDP port number), the Barricade redirects the external service request to the appropriate server (located at another internal IP address).

The WAN interface must have a fixed IP address to utilize this function. For example, if you set Type/Public Port to TCP/80 (HTTP or Web) and the Private IP/Port to 192.168.2.2/80, then all

4-15

ETWORKING AND CLIENT SERVICES

HTTP request from outside users will be transferred to 192.168.2.2. Therefore, by just entering the IP Address provided by the ISP, Internet users can access the service they need at the local address to which you redirect them.

Some of the more common TCP service ports include: HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.

Enabling Special Applications

Some applications require multiple connections, such as Internet gaming, videoconferencing, Internet telephony and others. These applications may not work when Network Address Translation (NAT) is enabled. If you need to run applications that require multiple connections, use the following screen to specify the additional public ports to be opened for each application.

Configuring Your Computer with Windows 2000

Step 1. Configure TCP/IP Settings

After you have completed the hardware setup, you need to configure your computer to connect to your Barricade. You also need to determine how your ISP issues your IP address. Many ISPs issue these numbers automatically, using a networking technology known as Dynamic Host Control Protocol, or DHCP. Other ISPs will specify your IP address and associated numbers, which you must enter manually. This is also known as a static IP address. How your ISP assigns your IP address determines how you will configure your computer.

Verifying Your TCP/IP Connection

After installing the TCP/IP communication protocol and configuring an IP address in the same network with the Barricade, you can use the Ping command to check if your computer is successfully connected to the Barricade. The following example shows how the Ping procedure can be executed in an MS-DOS window. First, execute the Ping command:

ping 192.168.2.1

If the following messages appear:

Pinging 192.168.2.1 with 32 bytes of data: Reply from 192.168.2.1: bytes=32 time=2ms TTL=64

a communication link between your computer and the Barricade has been successfully established.

Otherwise, if you get the following messages,

Pinging 192.168.2.1 with 32 bytes of data: Request timed out.

there may be something wrong in your installation procedure. Check the following items in sequence:

1. Is the Ethernet cable correctly connected between the Barricade and your computer?

The LAN LED on the Barricade and the Link LED of the network card on your computer must be on.

2. Is TCP/IP properly configured on your computer?

If the IP address of the Barricade is 192.168.2.1, the IP address of your PC must be from 192.168.2.2 - 192.168.2.254 and the default gateway must be 192.168.2.1.

LED Indicators

Power LED is Off • External power supply has failed or is

disconnected.

• Check connections between the Barricade, the external power supply, and the wall outlet.

• If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or external power supply.

However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet.

If you still cannot isolate the problem, then the external power supply may be defective. In this case, contact SMC Technical Support for assistance.

Caution: DO-NOT plug a phone jack connector into any RJ-45

port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable. All RJ-45 ports, except for the WAN port, support automatic MDI/MDI-X configuration. This means that you can use straight-through cable to attach the LAN ports to any network device. However, when connecting the WAN port to a broadband modem, you will need to use either straight-through or crossover cable, depending on the port type used on the modem.
