Chapter 5: Setting Up and Configuring the Router
Overview
The Router comes with a Web-based Utility that allows for easy set up and configuration. This chapter will explain
all of the functions in this Utility. (You can access the web-based utility by accessing 192.168.1.1.)
There are eleven main tabs in the Utility: System Summary, Setup, DHCP, System Management, Port
Management, Firewall, VPN, Log, Wizard, Support, and Logout. Sub-tabs are be available when you click one of
the main tabs. The tabs are described below:
System Summary Tab
The System Summary Tab displays the Router’s current status and settings. This information is read only. Some
words are underlined on this screen and, if you click them, will take you to the Utility page appropriate for that
word.
Setup Tab
From this tab, you can set the basic settings on your network. The screens available from this tab include:
Network. Enter the Internet connection and network settings on this screen.
Password. From this screen, you can change the Router’s password on this screen. For network security, you
should always change the password from its default setting.
Time. Change the time shown on the network from this screen.
DMZ Host. The DMZ (Demilitarized Zone) Host feature allows one network PC to be exposed to the Internet to
use special-purpose services such as Internet gaming or video conferencing.
Forwarding. Port forwarding can be used to set up public services on your network. You may use this function
to establish a Web server or FTP server via an IP Gateway.
UPnP. UPnP forwarding, set up on this screen, can be used to set up public services on your network.
One-to-One NAT. Like the DMZ feature, One-to-One NAT opens the NAT firewall for one computer, but does it
only for one Internet address. This feature is administered through this screen.

MAC Clone. Some ISPs require that you register a MAC address. From this screen, you can “clone” your
network adapter's MAC address onto the Router. This prevents you from having to call your ISP to change the
registered MAC address to the Router's MAC address.
DDNS. DDNS (Dynamic DNS) service, on this screen, allows you to assign a fixed domain name to a dynamic
Internet IP address. This allows you to host your own Web, FTP or other type of TCP/IP server in your network.
Advanced Routing. The Router's dynamic routing feature can be set up on this screen to automatically adjust
to physical changes in the network's layout.
DHCP Tab
Setup. From this screen, you can enable/disable the DHCP server, set up client lease time, DHCP IP Range,
and the WINS Server IP address.
Status. This Status page is available to review DHCP Server Status.
System Management Tab
Dual WAN. The Dual WAN feature allows you to use two Broadband connections at once, specifying between
using one as a Primary connection, with Smart Link Backup, and using both connections in concert, with Load
Balance.
SNMP. SNMP, or Simple Network Management Protocol, is a network protocol that provides network
administrators with the ability to monitor the status of the Router and receive notification of any critical
events as they occur on the network. SNMP can be managed from this screen.
Diagnostic. From this screen, you can use the Router’s two built-in tools to troubleshoot network problems.
Factory Default. The “Factory Default” button on this screen can be used to clear all of your configuration
information and restore the Router to its factory default settings. Only use this feature if you wish to discard
all other configuration preferences.
Firmware Upgrade. Users can use the function on this screen to upgrade the Router’s firmware to the newest
version.
Restart. The recommended method of restarting your Router is to use the “Restart Router” button on this
screen. Restarting with this button will send out your log file before the box is reset.
Setting Backup. This screen allows you to make or import a backup file of your Preferences file for the Router.
DDNS:
the capability of having a website, FTP, or e-mail
server-with a dynamic IP address-use a fixed domain name
Domain:
a specific name for a network of computers
