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.

4Features
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.
Features
BROADBAND MODEM AND IP SHARING
Connects multiple computers to a broadband (cable or DSL) modem to share the
Internet connection.

Features 5
ETHERNET SWITCH
Allows you to quickly and easily share an Internet connection with multiple
computers and devices.
VPN SUPPORTED
Supports multiple and concurrent IPSec and PPTP pass-through sessions, so
multiple users behind the router can access corporate networks through various
VPN clients more securely.
ADVANCED FIREWALL AND PARENTAL CONTROL FEATURES
The Web-based user interface displays a number of advanced network
management features including:
Content filtering—Easily applied content filtering based on MAC address, IP
address, URL, or domain name.
Filter scheduling—Filters can be scheduled to be active on certain days or for a
duration of hours and minutes.
Network Address Translation (NAT)—Allows your networked computers to
share a single IP address and protects you from outside intruders gaining access to
your private network.
DHCP SERVER SUPPORTED
All networked computers can retrieve TCP/IP settings automatically from the
router.
WEB-BASED MANAGEMENT
The router is configurable through any network computer’s Web browser.
ACCESS CONTROL SUPPORTED

Internet users.
SPECIAL APPLICATIONS SUPPORTED
Special applications requiring multiple connections are supported, such as
Internet gaming, video conferencing, and Internet telephony. The router can
detect the application type and open a multi-port tunnel for it.

6Features
DMZ HOST SUPPORTED
Allows a networked computer to be fully exposed to the Internet. This function is
used when the Special Applications feature is insufficient to allow an application
to function correctly.

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.

8Setting up 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).
Web-based management utility
The router has a Web-based management utility which is operating system
independent. You can configure your router through a Java Script enabled Web
browser in Windows, Macintosh, Linux, or UNIX-based platforms.
START UP AND LOG IN
To access the Web-based management utility:
1Open your Web browser and enter the IP address of the router into the
Location (for Netscape) or Address (for Internet Explorer) field, then press
Enter. The default IP address of the router is 192.168.0.1
For example, type 192.168.0.1
After the connection is established, the logon screen opens.
2To log in as an administrator, enter the user name of admin and leave the
password field blank (default), then click OK. The Web management Home
screen opens.
