Chapter 1: Introduction

Welcome

Thank you for choosing the 10/100/1000 4-Port VPN Router. The Linksys 10/100/1000 4-Port VPN Router is an
advanced Internet-sharing network solution for your small business needs. Like any router, it lets multiple
computers in your office share an Internet connection. But the 10/100/1000 4-Port VPN Router allows you to
connect gigabit-equipped PCs for gigabit networking, as well as including four 10/100/1000 ports for network
connectivity.
The Virtual Private Network (VPN) capability creates encrypted “tunnels” through the Internet, allowing up to 50
remote office or traveling users to securely connect into your office network from off-site. Users connecting
through a VPN tunnel are attached to your company's network — with secure access to files, e-mail, and your
intranet — just as if they were in the building. You can also use the VPN capability to allow users on your small
office network to securely connect out to a corporate network.
The 10/100/1000 4-Port VPN Router can serve as a DHCP Server, and has a powerful SPI firewall to protect your
PCs against intruders and most known Internet attacks. It can be configured to filter internal users' access to the
Internet, and has IP address filtering so you can specify exactly who has access to your network. Configuration is
a snap with the web browser-based configuration utility.
As the heart of your small office network, the 10/100/1000 4-Port VPN Router gives you the connection reliability
your business needs.
