•Follow the Installation Guide and this User Guide carefully. Follow the
correct procedures when setting up the router.

Introduction to broadband router
technology

A rout er is a device that forwards data packets from a source to a destination using
IP addresses, not MAC addresses. A router forwards data from the Internet to a
particular computer on your network.

The information that makes up the Internet gets moved around using routers.
When you click on a link on a Web page, you send a request to a server to show
you the next page. The information that is sent and received from your computer
is moved from your computer to the ser ver using routers. A router also determines
the best route that your information should follow to ensure that the information
is delivered correctly.

A router controls the amount of data that is sent through your network by
eliminating information that should not be there. This provides security for the
computers connected to your router, because computers from the outside cannot
access or send information directly to any computer on your network. The router
determines which computer the information should be forwarded to, then sends
it. If the information is not intended for any computer on your network, the data is
discarded. This keeps unwanted or harmful information from accessing or
damaging your network.

Firewalls

A firewall is a device that is set up between your computer and the Internet which
prevents unauthorized access to or from your network. A firewall can be a
computer using firewall software or a device built specifically to act as a firewall.
In most circumstances, a firewall is used to prevent unauthorized Internet users
from accessing your network.

A firewall analyzes all of the information moving to and from your network and
analyzes each piece of data and checks it against a set of criteria that the
administrator sets. If any data does not meet the criteria, that data is blocked and
discarded. If the data meets the criteria, the data is passed through. This is called
packet filtering.

A firewall can also run specific security functions based on the type of software or
type of port that is being used. For example, a firewall can be configured to work
with an FTP or Telnet server, or with specific UDP or TCP ports to allow certain
software or games to work correctly over the Internet.

LANs and WANs

A Local Area Network (LAN) is several computers connected together within a
small area such as a building or group of buildings. A collection of LANs connected
over a large area is called a Wide Area Network (WAN).

Although there are many ways to connect computers together, the most common
way is Cat-5 cable (UTP or STP twisted pair wire). Wireless networks, which use
radio waves instead of wires, are becoming more common. Each computer must
have a Network Interface Card (NIC), which transfers the data between computers.
A NIC can be a 10 Mbps, 10/100 Mbps, or 10/100/1000 Mbps network card.

Most networks use hardware devices such as hubs or switches to connect
computers. A hub takes any data arriving through each port and forwards the data
to all other ports. A switch is more sophisticated, in that a switch can determine
the destination port for a specific piece of data. A switch minimizes network traffic
overhead and speeds up communication over a network.

Setting up the router

Network settings

To use the router, you must correctly configure the network settings of your
computers. The default IP address of the router is 192.168.0.1, and the default
subnet mask is 255.255.255.0. These addresses can be changed as needed, but
the default values are used in this manual. If the TCP/IP environment of your
computer has not yet been configured, see “Configuring your computers” on page
45, for information.

We recommend that you configure your computers to obtain TCP/IP settings
automatically from the DHCP server feature of the router.

Since the IP address of the router is 192.168.0.1, the IP address of your computer
must be 192.168.0.X (where “X” is a number between 2 and 254.) Each computer
on your network must have a different IP address within that range. The default
gateway must be 192.168.0.1 (the IP address of the router).

CONFIGURING A VIRTUAL SERVER

The router can be configured as a virtual server so that remote users accessing
Web or FTP services with a public IP address can automatically be redirected to
local servers in the LAN (Local Area Network).

The router firewall feature filters out unrecognized packets to protect your LAN so
that all computers networked with the router are invisible to the outside world. If
you want, you can make some of the LAN computers accessible from the Internet
by enabling Virtual Server. Depending on the requested service, the router
redirects the external service request to the appropriate server within the LAN
network.

The router is also capable of port-redirection. Port-redirection takes incoming
traffic to a particular port and redirects it to a different port on the server
computer.

Each virtual service that is created are listed at the bottom of the screen in the
Virtual Servers List. Pre-defined virtual services are already in the table. You can
use them by enabling them and assigning the server IP to use that particular
virtual service.

To configure a virtual server:

1 Access the Configuration menu by following the instructions in To access

the Web-based configuration utility: on page 13.

Click this icon to edit the virtual service.

Click this icon to delete the virtual service.

Example #2:

If you have an FTP server that you wanted Internet users to access by WAN port
2100 and only during the weekends, you would need to enable it as such. The FTP
server is on LAN computer 192.168.0.30, and uses port 21, TCP.

Name: FTP Server
Private IP: 192.168.0.30
Protocol Type: TCP
Private Port: 21
Public Port: 2100
Schedule: From: 01:00AM to 01:00AM, Sat to Sun

All Internet users who want to access this FTP Server must connect to it from port

2100. This is an example of port redirection and can be useful in cases where there
are many of the same servers on the LAN network.
