DSL-500 ADSL Router User’s Guide

vii

About This Guide

Thank you for choosing the DSL-500 ADSL Router. The DSL-500 will provide your private small office or
home network with convenient Internet access and rapid download speeds while improving network efficiency
and security. D-Link strives to provide cost effective broadband access devices that are easy to use and upgrade
for small office and home networks.

If you would like to set up the device quickly in order to verify that the ADSL connection to the WAN (wide
area network) is working properly, please read the Quick Installation Guide included in the DSL-500 package.

This user’s guide provides instructions on how to install the DSL-500 ADSL Router and use it to connect several
PCs on an Ethernet LAN (Local Area Network) to the Internet. For the sake of simplicity, this document uses the
terms Router (first letter upper case) to refer specifically to the DSL-500 ADSL Router, and router (first letter
lower case) to refer to all such devices including the DSL-500.

DSL services are provided by many different types of business entities such as telephone companies, Internet
service providers (ISPs), DSL resellers and others. ADSL service is sometimes bundled together with some form
of network service such as an ISP account. This guide uses the generic terms ADSL service provider or network
service provider to refer to any or all businesses that provide ADSL service or Internet account services.

Furthermore it is assumed that the reader has some familiarity with Ethernet networks, networking devices,
routing protocols and the TCP/IP suite of protocols.
