NTRODUCTION

Congratulations on your purchase of the Barricade ADSL Router. 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 Barricade ADSL Router

The Barricade ADSL Router provides Internet access to multiple users by
sharing a single-user account. This new technology provides many secure
and cost-effective functions. It is simple to configure and can be up and
running in minutes.

Features and Benefits

1

• Internet connection to an ADSL modem via an RJ-11 ADSL port

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

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

mapping

1-1

I

NTRODUCTION

• Firewall with Stateful Packet Inspection, client privileges, intrusion
detection, and NAT

• 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, email, 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

Applications

Many advanced networking features are provided by the Barricade ADSL
Router:

•Fast Ethernet LAN

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

• Internet Access

This device supports Internet access through an ADSL connection.
Since many DSL providers use PPPoE or PPPoA to establish
communications with end users, the Barricade ADSL Router includes
built-in clients for these protocols, eliminating the need to install these
services on your computer.

1-2

A

PPLICATIONS

• Shared IP Address

The Barricade ADSL Router 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 ADSL Router
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
ADSL Router 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 ADSL Router supports security features that deny
Internet access to specified users, or filter all requests for specific
services that the administrator does not want to serve. The Barricade
ADSL Router’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.

Attach to Your Network Using Ethernet Cabling

The four LAN ports on the Barricade ADSL Router 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.

Use RJ-45 cables to connect any of the four LAN ports on the Barricade
ADSL Router to an Ethernet adapter on your PC. Otherwise, cascade any
of the LAN ports on the Barricade ADSL Router 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 ADSL Router.

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 Adapter

Plug the power adapter into the power socket on the rear of the Barricade
ADSL Router, and the other end into a power outlet.

Check the power indicator on the front panel is lit. If the power i
not lit, refer to

In case of a power input failure, the Barricade ADSL Router will
automatically restart and begin to operate once the input power is restored.

ONFIGURING

After completing hardware setup by connecting all your network devices,
you need to configure your computer to connect to the Barricade ADSL
Router. 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.

Depending on your operating system see:

TCP/IP Configuration

To access the Internet through the Barricade ADSL Router, you must
configure the network settings of the computers on your LAN to use the
same IP subnet as the Barricade ADSL Router. The default IP settings for
the Barricade ADSL Router are:

IP Address 192.168.2.1

Subnet Mask 255.255.255.0

DHCP function Enable

DHCP IP Pool Range 192.168.2.2 to

192.168.2.254

Note: These settings can be changed to fit your network requirements,

but you must first configure at least one computer to access the
Barricade ADSL Router’s web configuration interface in order to
make the required changes. (See “Configuring the Barricade ADSL

Virtual Server

If you configure the Barricade ADSL Router 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 ADSL Router redirects the
external service request to the appropriate server (located at another
internal IP address).

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 HTTP requests from
outside users will be transferred to 192.168.2.2 on port 80. 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.

RIP sends routing-update messages at regular intervals and when the
network topology changes. When a router receives a routing update that
includes changes to an entry, it updates its routing table to reflect the new
route. RIP routers maintain only the best route to a destination. After
updating its routing table, the router immediately begins transmitting
routing updates to inform other network routers of the change.

Netmask The subnetwork associated with the destination.

This is a template that identifies the address bits in the
destination address used for routing to specific subnets. Each bit
that corresponds to a “1” is part of the subnet mask number;
each bit that corresponds to “0” is part of the host number.

FIREWALL

The Barricade ADSL Router’s firewall inspects packets at the application
layer, maintains TCP and UDP session information including time-outs
and the number of active sessions, and provides the ability to detect and
prevent certain types of network attacks.

Network attacks that deny access to a network device are called
Denial-of-Service (DoS) attacks. 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 resources.

The firewall function of the Barricade ADSL Router protects against the
following DoS attacks: 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. (See page 4-47 for details.)

The firewall does not significantly affect system performance, so we advise
leaving it enabled to protect your network. Select Enable and click the
“SAVE SETTINGS” button to open the Firewall submenus.

ONFIGURING THE BARRICADE

• Stateful Packet Inspection

This is called a “stateful” packet inspection because it examines the
contents of the packet to determine the state of the communications; i.e., it
ensures that the stated destination computer has previously requested the
current communication. This is a way of ensuring that all communications
are initiated by the recipient computer and are taking place only with
sources that are known and trusted from previous interactions. In addition
to being more rigorous in their inspection of packets, stateful inspection
firewalls also close off ports until connection to the specific port is
requested.

When particular types of traffic are checked, only the particular type of
traffic initiated from the internal LAN will be allowed. For example, if the
user only checks “FTP Service” in the Stateful Packet Inspection section,
all incoming traffic will be blocked except for FTP connections initiated
from the local LAN.

Stateful Packet Inspection allows you to select different application types
that are using dynamic port numbers. If you wish to use the Stateful Packet
Inspection (SPI) to block 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 Fragmentation, TCP
Connection, UDP Session, FTP Service, H.323 Service, or TFTP Service.
