Chapter 1: Introduction
Welcome
Thank you for choosing the 4-Port Gigabit Security Router with VPN. The Linksys 4-Port Gigabit Security Router
with VPN 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.
The 4-Port Gigabit Security Router with VPN also features a built-in 4-Port full-duplex 10/100/1000 Ethernet
switchtoconnect four PCs directly,oryoucanconnect more hubs and switchesto create as big anetwork as you
need.
The Virtual Private Network (VPN) capability creates encrypted “tunnels” through the Internet, allowing up to 5
remote offices and 5 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 QoS features provide consistent voice and
video quality throughout your business.
The 4-Port Gigabit Security Router with VPN 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 and MAC address filtering so you can specify exactly who has access to your
network. Configuration is a snap with the web browser-based configuration utility.
This user guide will give you all the information you need to connect, set up, and configure your Router.
