Chapter 1: Introduction
Welcome
Broadband Firewall Router with 4-Port Switch/VPN Endpoint
Chapter 1: Introduction
Welcome
Thank you for choosing the Broadband Firewall Router with 4-Port Switch/VPN Endpoint. This Router provides
your network with a high-security way to share a high-speed Internet connection as well as resources, including
files and printers.
How is this done? Inside this Router you have the Internet-access sharing ability of a standard Linksys Router,
along with the network expandibility of a 4-Port 10/100 Switch, and the network security functions of VPN.
But what does all of this mean?
At the core of this Router, is a standard, Linksys Router, providing you the ability to share your broadband,
Internet access within your network. This also comes with the protection of a firewall and the easy setup and
configuration you’ve come to expect from a Linksys Router. Add to that the network expandibility of a 4-port
10/100 Switch. The four ports in the back of the Router are all auto-detecting, meaning that the Router can tell if
you’re connecting a straight-through or cross-over cable, making this easier to use than ever. Finally, adding VPN
network security to the Router allows you to secure data, not just behind the Router, but as it is transmitted over
the Internet. VPNs, or Virtual Private Networks, create virtual tunnels that connect your PC to another across the
Internet, keeping the data secure as it passes from one to another.
In this User Guide, you’ll find all you need to setup, configure, and use the Router, including appendices
describing VPNs. Welcome to secure broadband networking.

Chapter 2: Your Virtual Private Network (VPN)
Why do I need a VPN?
Broadband Firewall Router with 4-Port Switch/VPN Endpoint
Chapter 2: Your Virtual Private Network (VPN)
Why do I need a VPN?
Computer networking provides a flexibility not available when using an archaic, paper-based system. With this
flexibility, however, comes an increased risk in security. This is why firewalls were first introduced. Firewalls help
to protect data inside of a local network. But what do you do once information is sent outside of your local
network, when emails are sent to their destination, or when you have to connect to your company's network
when you are out on the road? How is your data protected?
That is when a VPN can help. VPNs are called Virtual Private Networks because they secure data moving outside
of your network as if it were still within that network.
When data is sent out across the Internet from your computer, it is always open to attacks. You may already have
a firewall, which will help protect data moving around or held within your network from being corrupted or
intercepted by entities outside of your network, but once data moves outside of your network - when you send
data to someone via email or communicate with an individual over the Internet - the firewall will no longer protect
that data.
At this point, your data becomes open to hackers using a variety of methods to steal not only the data you are
transmitting but also your network login and security data. Some of the most common methods are as follows:
1) MAC Address Spoofing
Packets transmitted over a network, either your local network or the Internet, are preceded by a packet header.
These packet headers contain both the source and destination information for that packet to transmit efficiently.
A hacker can use this information to spoof (or fake) a MAC address allowed on the network. With this spoofed
MAC address, the hacker can also intercept information meant for another user.
2) Data Sniffing
Data "sniffing" is a method used by hackers to obtain network data as it travels through unsecured networks,
such as the Internet. Tools for just this kind of activity, such as protocol analyzers and network diagnostic tools,
are often built into operating systems and allow the data to be viewed in clear text.
3) Man in the middle attacks
Once the hacker has either sniffed or spoofed enough information, he can now perform a "man in the middle"
attack. This attack is performed, when data is being transmitted from one network to another, by rerouting the
packet: a unit of data sent over a network
VPN (Virtual Private Network): a security
measure to protect data as it leaves one
network and goes to another over the Internet

Chapter 2: Your Virtual Private Network (VPN)
What is a Virtual Private Network?
Broadband Firewall Router with 4-Port Switch/VPN Endpoint
data to a new destination. Even though the data is not received by its intended recipient, it appears that way to
the person sending the data.
These are only a few of the methods hackers use and they are always developing more. Without the security of
your VPN, your data is constantly open to such attacks as it travels over the Internet. Data travelling over the
Internet will often pass through many different servers around the world before reaching its final destination.
That's a long way to go for unsecured data and this is when a VPN serves its purpose.
What is a Virtual Private Network?
A VPN, or Virtual Private Network, is a connection between two endpoints - a VPN Router, for instance - in
different networks that allows private data to be sent securely over a shared or public network, such as the
Internet. This establishes a private network that can send data securely between these two locations or
networks.
This is done by creating a "tunnel". A VPN tunnel connects the two PCs or networks and allows data to be
transmitted over the Internet as if it were still within those networks. Not a literal tunnel, it is a connection
secured by encrypting the data sent between the two networks.
VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private network.
Using industry standard encryption and authentication techniques - IPSec, short for IP Security - the VPN creates
a secure connection that, in effect, operates as if you were directly connected to your local network. Virtual
Private Networking can be used to create secure networks linking a central office with branch offices,
telecommuters, and/or professionals on the road (travelers can connect to a VPN Router using any computer with
VPN client software that supports IPSec, such as SSH Sentinel.)
There are two basic ways to create a VPN connection:
•VPN Router to VPN Router
•Computer (using VPN client software that supports IPSec) to VPN Router
The VPN Router creates a “tunnel” or channel between two endpoints, so that data transmissions between them
are secure. A computer with VPN client software that supports IPSec can be one of the two endpoints. Any
computer with the built-in IPSec Security Manager (Windows 2000 and XP) allows the VPN Router to create a VPN
tunnel using IPSec (refer to “Appendix F: Configuring IPSec between a Windows 2000 or XP PC and the VPN
Router”). Other versions of Microsoft operating systems require additional, third-party VPN client software
applications that support IPSec to be installed.

Computer (using VPN client software that supports IPSec) to VPN Router
Broadband Firewall Router with 4-Port Switch/VPN Endpoint
VPN Router to VPN Router
An example of a VPN Router-to-VPN Router VPN would be as follows. At home, a telecommuter uses his VPN
Router for his always-on Internet connection. His router is configured with his office's VPN settings. When he
connects to his office's router, the two routers create a VPN tunnel, encrypting and decrypting data. As VPNs
utilize the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection to the
central office's network, as if he were physically connected.
Computer (using VPN client software that supports IPSec) to VPN Router
The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling businesswoman
dials up her ISP. Her notebook computer has VPN client software that is configured with her office's VPN settings.
She accesses the VPN client software that supports IPSec and connects to the VPN Router at the central office. As
VPNs utilize the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure
connection to the central office's network, as if she were physically connected.
For additional information and instructions about creating your own VPN, please visit Linksys’s website at
www.linksys.com or refer to “Appendix F: Configuring IPSec between a Windows 2000 or XP PC and the VPN
Router.”

Figure 2-2: Computer to VPN Router
IMPORTANT: You must have at least one VPN Router on
one end of the VPN tunnel. At the other end of the VPN
tunnel, you must have a second VPN Router or a computer
with VPN client software that supports IPSec.
