NTRODUCTION

Congratulations on your purchase of a 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 the Internet at the lowest possible cost, the Barricade

™ Broadband Router is the convenient, easy solution.

About the Barricade

The Barricade provides Internet access to multiple users by sharing a single-user account. The Barricade features a

WAN interface that allows

you to connect either a DSL or cable

modem. The

Barricade

provides

extensive firewall protection and Virtual Private Network (VPN) services. The Barricade provides many cost-effective functions and management

benefits. It is simple to configure and can be up and running in minutes.

Features and Benefits

• Internet connection to DSL or cable modem via a 10/100 Mbps WAN

port

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

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

mapping

NTRODUCTION

1-2

• Firewall with Stateful Packet Inspection, client privileges, hacker prevention, DoS, and NAT

• NAT also enables multi-u s er access with a single-us er account, and virtual server functionality (providing protected access to Internet services such as web, mail, FTP, and Telnet)

• Virtual Private Network support using PPTP, L2TP, or IPSec pass-through

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

• Parental controls allows the user to limit certain web sites

• Email alerts when the users network is being compromise

• Easy setup through a web browser on any operating system that supports TCP/IP

• Compatible with all popular Internet applications

NTRODUCTION

1-3

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 a DSL or cable 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 Barricad e shares a single IP address with up to 253 users. Using only one ISP account, multiple users on your network can simultaneously browse the Internet.

•Virtual Server

If you have a static 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 the static IP address. Then, depending on the requested service (or port number), the Barricade routes the request to the appropriate server (at an internal network IP address). This secures your network from direct attac k by hac kers , and provides more flexible management by allowing you to change internal network IP addresses without affecting outside access to your network.

NTRODUCTION

1-4

• User-Definable Application Sensing Tunnel

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

• DMZ Hosts 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 deny Internet access to specified users, or drop requests for specific services. The Barricad e’s firewall also blocks common hack er 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 netw or k). The VPN protocols supported by the Barricade are briefly described below.

NTRODUCTION

1-5

• 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.

Hardware Description

The Barricade Broadband Router ma y be connected to the Internet or to a remote site using its RJ-45 W AN port. It may be connected directly to your PC or to a local area network using any of the four 10/100 autosensing switch ports.

These RJ-45 ports auto-negotiate the operating speed (10/100 Mbps) and the duplex mode (half/full duplex).

Access speed to the Internet depends on your service type. Full-rate Asymmetric Digital Subscriber Line (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; Cable modems provide up to 36 Mbps downstream and 2 Mbps upstream. However, you should note that the actual rate provided by specific service providers may vary dramatically from these upper limits.

Though Internet access speed 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 LED indicators on the front panel that simplify installation and network troubleshooting.

LAN

LAN IP

Use the LAN menu to configure the LAN IP address for the Barricade and to enable the DHCP server for dynamic client address allocation.

Set a period for the lease time if required. For home networks this may be set to “Forever”, which means there is no time limit on the IP address lease.

IP Address Pool

A dynamic IP start address may be specified by the user, e.g. 192.168.2.100 (default value). Once this start IP address has been assigned, IP addresses running from 192.168.2.100 to 192.168.2.199 will be part of the dynamic IP address pool. IP addresses from 192.168.2.2 to 192.168.2.99, and

192.168.2.200 to 192.168.2.254 will be available as static IP addresses.

DVANCED SETUP

4-18

Remember not to include the addres s of the Barricade in the client address pool. Also remember to configure your client PCs for dynamic IP address allocation.

NAT

Address Mapping

Allows one or more public IP addresses to be shared by multiple internal users. Enter the Public IP address you wish to share into the “Global IP” field. Enter a range of internal IPs that will share the global IP into the “from” field.

ONFIGURING THE BARRICADE

4-19

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 w ords , depending on the requested service (TCP/UDP port number), the Barricade redirects the external service request to the appropriate internal server and port.

The WAN interface should have a fixed IP address to properly utilize this function. For example, if you set Type/Public Port to TCP/80 (HTTP or web) and the Private IP/P ort to 192.168.2.2/8080, then all HTTP requests from outside users will be transferred to port 8080 on 192.168.2.2. Therefore, by just entering the IP Address provided by the ISP, Internet users can access the service you provide at the internal address and port to which the Barricade redirects them.

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

Intrusion Detection

DVANCED SETUP

4-28

The Intrusion Detection feature of the Barricade limits the access of the incoming traffic from the WAN port. When the SPI feature is tur ned on, all the incoming packets will be blocked unless certain types of traffic types are checked by the users. When the user checkes certain types of traffic, only the particular type of traffic initiated from the Internal LAN will be allowed. For example, if the user only checks “FTP service” from the Stateful Packet Inspection page, all the incoming traffic will be blocked except the FTP connection initiated from the local LAN.

• Stateful Packet Inspection

This option allows you to select different application types that are using dynamic port numbers. If you need to use the Stateful Packet Inspection (SPI) for blocking packets, click on the “Yes” radio button in the “Enable SPI and Anti-DoS firewall protection” field and then check the inspection type that you need, such as Pac k et F ragmentation, TCP Connection, UDP Session, FTP Service, H.323 Service and TFTP Service.

• Hacker Prevention Feature

The Barricade firewall inspects packets at the application layer, and maintains TCP and UDP session information, including timeouts and number of activ e sessions , provides the ability to detect and prev ent certain types of network attacks such as DoS attacks.

Network attacks that deny access to a network device are called denial-of-service (DoS) attacks. Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resource.

By using the above inspected information and timeout/threshold critieria, the Barricade provides the following DoS attack preventions: Ping of Death (Ping flood) attack, SYN flood attack, IP fragment attack (T eardrop Attack), Brute-force attack, Land Attack, IP Spoofing attack, IP with zero length, TCP null scan (Port Scan Attack), UDP port loopback, Snork Attack etc..

Note: The firewall does not significantly affect system performance, so

we advise enabling the prevention features to protect your network users.

Configuring Your Computer with Windows NT 4.0

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 need to determine how your ISP issues your IP address. Many ISPs issue these numbers automatically using a networking technology known as Dynamic Host Configuration Protocol, or DHCP. Other ISPs will specify your IP address and associated numbers, whic h yo u must enter man ually. This is known as a static or fixed IP address. Ho w your ISP assigns your IP address determines how you will configure your computer.

Here is what to do:

1. From the Windows desktop click “Start/ Settings/Control Panel.”

2. Double-click the “Network” icon.

Verifying Your TCP/IP Connection

After installing the TCP/IP communication protocols and configuring an IP address in the same network as the Barricade, use the “Ping” command to check if your computer has 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 a message similar to the following appears:

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.

If you get the following message,

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 the 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.

If you can successfully Ping the Barricade you are now ready to connect to the Internet!
