Congratulations on your purchases 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
