Chapter 1: Introduction

Welcome

10/100 16-Port VPN Router

Chapter 1: Introduction

Welcome

Thank you for choosing the 10/100 16-Port VPN Router. The Linksys 10/100 16-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 16 ports on this Router feature unprecedented versatility. Two

are dedicated Internet ports that let you connect a second Internet line as a backup to ensure that you're never

disconnected. Or, you can use both Internet ports at the same time, and let the router balance your office's

requirements between them for maximum bandwidth efficiency.

Not enough? Up to five of the thirteen full-duplex switched 10/100 Ethernet ports can be reconfigured as Internet

ports, for an up to seven-port failover or load balanced redundancy! Finally, a dedicated DMZ port gives you a

publicly accessible channel so you can set up a web or FTP server, unimpeded by the powerful security features

of the Router.

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 16-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 connection-redundant Linksys 10/100 16-Port VPN Router gives you

the connection reliability your business needs.

Use the instructions in this Guide to help you connect the Router, set it up, and configure it to bridge your different

networks. These instructions should be all you need to get the most out of the 10/100 16-Port VPN Router.

An Introduction to LANs

10/100 16-Port VPN Router

Chapter 2: Networking Basics

An Introduction to LANs

A Router is a network device that connects two networks together.

The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet. The

Router processes and regulates the data that travels between these two networks.

The Router’s Stateful Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology protects

your network of PCs so users on the Internet cannot “see” your PCs. This is how your LAN remains private. The

Router protects your network by inspecting the first packet coming in through the Internet port before delivery to

the final destination on one of the Ethernet ports. The Router inspects Internet port services like the web server,

ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate PC on the

LAN side.

The Use of IP Addresses

IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers,

requires an IP address to identify its location, or address, on the network. This applies to both the Internet and

LAN connections.

There are two ways of assigning IP addresses to your network devices.

A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a

static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will

always have that same IP address until you change it. Static IP addresses are commonly used with network

devices such as server PCs or print servers.

If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have

assigned a static IP address to your account. If so, you will need that static IP address when configuring the

Router. You can get the information from your ISP.

A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called

dynamic because they are only temporarily assigned to the PC or other device. After a certain time period, they

expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the

DHCP server will assign it a new dynamic IP address.

Dynamic IP address

: a temporary IP

address assigned by a DHCP server.

Static IP address

: a fixed address

assigned to a computer or device that

is connected to a network.

NAT (Network Address Translation)

:

NAT technology translates IP

addresses of a local area network to a

different IP address for the Internet.

DHCP (Dynamic Host Configuration

Protocol)

: a protocol that lets one

device on a local network, known as a

DHCP server, assign temporary IP

addresses to the other network

devices, typically computers.

LAN (Local Area Network)

: the

computers and networking products

that make up the network in your home

or office.

SPI (Stateful Packet Inspection)

firewall

: a technology that inspects

every incoming packet of information

before allowing it to enter the network.
