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

mapping

1-1

I

NTRODUCTION

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

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 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 Barricade 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.

I

NTRODUCTION

•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 attack b y hack ers, and
provides more flexible management by allowing you to change
internal network IP addresses without affecting outside access to your
network.

1-3

I

NTRODUCTION

• 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 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.

• Virtual Private Network

1-4

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.

I

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.

Please fill out and return the Warranty Registration Card to SMC, or
register on SMC’s web site at www.smc.com or www.smc-europe.com.
The Barricade Broadband Router is covered by a limited lifetime warranty.

Hardware Description

The Barricade Broadband Router may be connected to th e 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 ser vice 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.

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.

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 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.

The Intrusion Detection feature of the Barricade limits the access of the
incoming traffic from the WAN port. When the SPI feature is turned 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 Packet 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 active sessions , pro vides the ability to detect and prevent 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.

Configuring Your Computer with Windows XP

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
Configuration 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.

Here is what to do:

1. From the Windows
desktop, click the “start”
button. Choose “Control
Panel.”

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:

TCP/IP

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!
