INTRODUCTION
With the explosive growth of the Internet, accessing information
and services at any time, day or night has become a standard
requirement for most people. The era of the standalone PC is
waning. Networking technology is moving out of the exclusive
domain of corporations and into homes with at least two
computers.
Broadband network access is also gaining ground. However,
allowing more than two computers to access the Internet at the
same time means less affordable, higher costs. Thus, there is a
need to share one legal IP address over a single Internet
connection to link the home with the Internet.
The scarcity of IP addresses and using a shared Internet
connection through an Internet sharing device can solve high
network access costs. All linked computers can make full use of
broadband capabilities over such a device.
This device not only comes equipped with a wide range of
features, but also can be installed and configured right out of
the box. This device supports a simple local area network and
Internet access share, offering great cost savings.
The local area network connects up home computers while also
allowing any of the computers to access the Internet, share
resources, or play online games—the basis of the family
computing lifestyle.
Applications:
Broadband Internet access:
Several computers can share one high-speed broadband
connection (LAN and WAN-Internet).
3
Resource sharing:
Share resources such as printers, scanners and other
peripherals.
File sharing:
Exchange data, messages, and distribute files thus making
good use of hard disk space.
Online gaming:
Through the local area network, online gaming and e-commerce
services can be easily setup.

Internet Broadband Router
Connect the Internet Broadband Router
1. Plug in one end of the network cable to the WAN port of the
four ports Internet Broadband Router, either the “X” or “II”
port to be connected, depends of what the broadband
modem specification is using.
2. Plug in one end of the network cable to the WAN port of the
four port Internet Broadband Router, the port need to
connect to hub/switch, using the crossover cable depends
on what the broadband modem specification needs.
3. Plug in the other end of the network cable to the Ethernet
port of the xDSL or Cable modem.
4. Use another network cable to connect to the Ethernet card
on the computer system, the other end of the cable
connects to the LAN port of the Internet Broadband Router.
Since the Internet Broadband Router has four ports, you
can connect up to four computers directly to the unit. There
you do not have to buy a switch to connect these
computers since one Internet Broadband Router functions
both as a connection-sharing unit and as a switch.

Check the installation
The control LEDs of the Internet Broadband Router are clearly
visible and the status of the network link can be seen instantly:
1. With the power source on, once the device is connected to
the broadband modem, the Power, CPU, LAN and WAN
port link LEDs of the Internet Broadband Router will light up
indicating a normal status.
2. By using a Straight through Cable on the four port
broadband router, the WAN’s “X” port must connect to MDI
uplink port, and the WAN’s “II” port must connect to MDII
regular port.
3. If the WAN Port’s Link indicator does not light up then
replace the RJ-45 cable that plugged onto WAN’s “X” port
to the “II” port or from the “II” port to the “X” port at the rear
or using a crossover cable to connect on the WAN port to
meet the specification need of the xDSL or Cable modem.

domain names are located and translated into Internet Protocol
(IP) addresses.
If your ISP provided at least one DNS Server IP Address, type
that IP Address in the Primary DNS address fields. You can
type up to another DNS Server IP Addresses. The Router will
utilize these for quicker access to functioning DNS Servers.
2-3 LAN
This section is to set the LAN’s IP Address and DHCP Service.
2-3-1 LAN Settings
The default value is 192.168.1.1 for the IP address and
255.255.255.0 for the Subnet Mask. And you can also change
the value for your
needs.
To enable the DHCP
server for dynamic IP
address allocation to
the clients PCs, click
the “Enable”. The
client can get the IP Addresses from a range from IP Pool
Starting Address to IP Pool Ending Address; also, you can
change the IP Pool range value.
The Lease Time is the amount of time a network user will be
allowed connection to the Router with their current dynamic IP
30
address. Enter the amount of time, in hours, days or weeks,
which the user will be “leased” this dynamic IP address.
You can enter your local domain name in the Local Domain
Name fields.
2-3-2 DHCP Client List
The DHCP client list allows you to see which clients are
connected to the Barricade via IP address, host name, and
MAC address.
2-4 NAT
Network Address Translation (NAT) allows multiple users at the
local site to access the Internet through a single public IP
address. NAT can also prevent hacker attacks by mapping local
addresses to public addresses for key services such as the
Web or FTP.
2-4-1 Special Application
Some applications require multiple connections, such as
Internet gaming, video conferencing, Internet telephony and
others. These applications cannot work when Network Address
Translation (NAT) is enabled. When users send this type of
request to your network via the Internet, the Router will forward
those requests to the appropriate PC. If you need to run
applications that require multiple connections, specify the port
normally associated with an application in the "Trigger Port"
field, select the protocol type as TCP or UDP, then enter the
public ports associated with the trigger port to open them for
inbound traffic.
31
zTCP (Transmission Control Protocol) - A method (protocol)
used along with the Internet Protocol (Internet Protocol) to
send data in the form of message units between
computers over the Internet. While IP takes care of
handling the actual delivery of the data, TCP takes care of
keeping track of the individual units of data (called packets)
that a message is divided into for efficient routing through
the Internet.
zUDP (User Datagram Protocol) - A communications
method (protocol) that offers a limited amount of service
when messages are exchanged between computers in a
network that uses the Internet Protocol (IP). UDP is an
alternative to the TCP and, together with IP, is sometimes
referred to as UDP/IP. Like the Transmission Control
Protocol, UDP uses the Internet Protocol to actually get a
data unit (called a datagram) from one computer to
another. Unlike TCP, however, UDP does not provide the
service of dividing a message into packets (datagram’s)
and reassembling it at the other end. Specifically, UDP
doesn't provide sequencing of the packets that the data
arrives in. This means that the application program that
uses UDP must be able to make sure that the entire
message has arrived and is in the right order. Network
applications that want to save processing time because
they have very small data units to exchange (and
therefore very little message reassembling to do) may
prefer UDP to TCP.

2-4-2 Virtual Server
Configure the Broadband Router as a virtual server to allow the
Router to watch outgoing data for specific port numbers. The IP
address of the computer that sends the matching data is
remembered by the Router, so that when the requested data
returns through the Router, the data is pulled back to the proper
computer by way of IP address and port mapping rules such as
the Web or FTP at the 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 Broadband Router
redirects the external service request to the appropriate server.
33
Example:
ID Server IP Mapping Port Type Comment
1 192.168.2.20 80 TCP Web Server
2 192.168.2.12 20 TCP FTP Server
3 192.168.2.12 21 TCP FTP Server
4 192.168.2.28 23 TCP Telnet Server
2-5 Firewall
The Broadband Router provides extensive firewall protection by
restricting connection parameters to limit the risk of hacker
attack, and defending against a wide array of common hacker
attacks.
The Broadband Router provides packet filtering rules by
restricting service ports, IP address or MAC address. However,
for applications those require unrestricted access to the Internet;
configure a specific client/server as a demilitarized zone (DMZ).
2-5-1 Block WAN Ping
When the "Block WAN Ping" activated, it is causing the public
WAN IP address on the Broadband Router not to respond to
ping commands. Pinging public WAN IP addresses is a
34
common method used by hackers to test whether the WAN IP
address is valid and supports a network.
2-5-2 Client Filtering
To block a certain client PCs accessing the Internet based on
time.
You can filter Internet access for local clients based on IP
addresses, application types, (i.e., HTTP port), and time of day.
For example, this screen shows that clients in the address
range 192.168.2.50-99 are permanently restricted from using
FTP (Port 21), while clients in the address range
192.168.2.110-119 are blocked from browsing the Internet (port
80) from Monday to Friday and from 0:00AM to 11:00 PM.
Example:
2-5-3 MAC Control
You can block certain client PCs accessing the Internet based
on MAC addresses.
35
2-5-4 DMZ (Demilitarized Zone)
If a local client PC cannot run an Internet application properly
from behind the NAT firewall, open the client up to unrestricted
two-way Internet access by defining a virtual DMZ Host.
