Important safety instructions
These precautions explain how to safely operate your new router, preventing
injury to you or to others, or damage to the router.
Warning - read this carefully before proceeding.
• Do not open the router or attempt to disassemble or modify it.
• Do not insert fingers or foreign objects into the router.
• Do not expose the router to rain, use it near water or in damp or wet
conditions, or place containers on it that contain liquids which might spill
into openings.
• Follow the Installation Guide and this User Guide carefully. Follow the
correct procedures when setting up the router.
Introduction to broadband router
technology
A router 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 server 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.

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.

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:

CONFIGURING FIREWALL RULES
Description
Firewall rules is an advanced feature used to deny or allow traffic from passing
through the router. It works in the same way as IP Filters with additional settings.
You can create more detailed access rules for the router. When virtual services are
created and enabled, they also display in firewall rules. Firewall Rules contain all
network firewall rules pertaining to IP (Internet Protocol).
The priorities of the Firewall Rules are listed in the firewall rules List at the bottom
of the screen, with the highest priority rules at the top and the lowest at the
bottom.
Note - The router MAC address filtering rules have precedence over the Firewall
Rules.
