Introduction

Congratulations on your purchase of the D-Link Broadband Router.
Your Broadband Router enables you to share your DSL or Cable Internet
connection with computers on your 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 Broadband Router allows 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 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 to ensure that games
and other Internet applications will run properly.
The 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 you 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 Broadband Router to
expose it to the Internet and ensure complete Internet application
compatibility even if specific ports are not known.
Unlike proxy server or NAT software that requires the software server
to remain visible on the Internet, no local computers are directly externally
visible when using the Broadband Router. Also the Broadband Router, like
broadband, is always on, removing the need to constantly boot a software
server when access is desired from a client.
Integrated DHCP services allow up to 253 users to get their IP address
automatically on boot up from the Broadband Router. Client machines
