Chapter 1 - Getting Started 

Thank you for purchasing the D-Link Broadband Router. Your 

Broadband Router enables you to share your DSL or Cable Internet 
connection with computers on your wired or wireless network. This guide 
will explain the features and functions of the Broadband Router to help you 
get the most out of your Internet experience.   
 

D-Link’s Wireless Broadband Router allows wireless LAN users to 

share a single Internet Connection while providing the safety and security 
of port blocking, packet filtering, and a natural firewall. Static address 
support, integrated DHCP, PPPoE, and device name support will allow it to 
connect to nearly any broadband provider whether Cable or DSL based, 
and at the same time simplify local area network settings.   

The Wireless Broadband Router provides two levels of security 

support. First, it masks local users’ IP addresses from others on the Internet 
making it much more difficult for a hacker to target a machine on your 
network. Secondly it can block and redirect certain ports to limit the 
services that outside users can access. Specific ports can be opened by the 
user to ensure that games and other Internet applications will run properly.   

The Wireless Broadband Router provides special pass through support 

for common VPN implementations. The Virtual Server feature allows you 
to expose HTTP, FTP, Game Servers and other local services to be 
accessible to Internet users located outside of the LAN. The 
User-Definable Application Sensing Tunnel feature allows the user to 
define the attributes to support special applications requiring multiple 
connections, such as Internet gaming, video conferencing, and Internet 
telephony. A DMZ setting can be applied to a single client behind the
