The Linksys EtherFast®Cable/DSL Router
Let the Linksys USBVPN and FirewallAdapter protect your PC and your com-
munications wherever you go. This easy-to-pack, lightweight, network inter-
face with advanced safety and security features connects you to the Internet
through any broadband connection (cable, DSL, or your hotel's fast Internet
service), and protects your PC from most known Internet attacks with a pow-
erful Stateful Packet Inspection firewall. You can also optionally block Java,
Active X, and Cookies -- known points of entry for hackers.
The Adapter connects to virtually any PC through the USB port, and requires
no external power supply. Once you're connected, you can establish a Virtual
Private Network tunnel from your PC to a corporate network using the popular
IPSec VPN standard, and your transmitted data will be protected by govern-
ment-spec DES or Triple-DES encryption.
It's also a perfect traveling companion to the Linksys Firewall Router
(BEFSX41) orVPN Router (BEFVP41) on your home or small office network.
You can securely connect to your home resources to retrieve files, or check
your local email. Once you're connected overVPN, it's just like being attached
to the local network.
With the Linksys USB VPN and Firewall Adapter protecting your PC and
communications, you'll have one less thing to worry about when you're travel-
ing.
•A USB-attached network interface with firewall safety and a secure com-
munication link
•Establishes an IPSec Virtual Private Network tunnel to your corporate net-
work
•Advanced firewall with Stateful Packet Inspection protects your PC from
Internet attacks, wherever you connect
•USB interface -- works with virtually any PC

Ethernet The Ethernet port is where you connect the Ethernet cable to
a Router or cable or DSL modem. (See Figure 2-2.)
The Reset Button
Briefly pressing the Reset Button (see Figure 2-2) will refresh the Adapter’s
connections, potentially clearing any jammed links.
Pressing the Reset Button and holding it in for a few seconds will clear all of
the Adapter’s data. This should be done only if you are experiencing heavy
routing problems, and only after you have exhausted all of the other trou-
bleshooting options. By resetting theAdapter, you run the risk of creating con-
flicts between your PC’s actual IP Address and what the Adapter thinks its IP
Address should be. You may be forced to reboot the entire system. Please
restart your computer after resetting the Adapter.
If the Adapter locks up, simply power it down for three to five seconds by
removing the USB cable from the Adapter’s USB Port. Reconnect the USB
cable to the Adapter’s USB port and check your connection status again.

Link/Act Green. The Link/Act LED serves two purposes. If the LED is con-
tinuously lit, the Adapter is successfully connected. If the LED is
flickering, the Adapter is actively sending or receiving data.
Full/Col Green. The Full/Col LED also serves two purposes. If this LED is
lit up continuously, the connection is running in Full Duplex mode.
If the LED flickers, the connection is experiencing collisions.
If this LED flickers too often, there may be a problem with your
connection. See “Appendix A: Troubleshooting” if you encounter
this problem.
100 Orange. The 100 LED lights up when a successful 100Mbps con-
nection is made.
If this LED does not light up, then your connection speed is 10
Mbps.

1. Before you begin, make sure that all of your hardware is powered off,
including the Adapter, PCs, cable or DSL modem, and/or Router.
2. Connect one end of the USB cable to the USB port on the Adapter (see
Figure 3-2) and the other end of the USB cable to a USB port on your PC
(see Figure 3-3.)
3. Connect one end of an Ethernet cable to the Ethernet port on the Adapter,
and the other end to an Ethernet port (LAN port) on a Router. If you are not
using a Router, you can connect it directly to a cable or DSL modem.
•The USB LED will light up green as soon as the Adapter is connected cor-
rectly to the PC. (The LED is shown in Figure 2-5.)
•The Diag LED will light up red for a few seconds when the Adapter goes
through its self-diagnostic test. This LED will turn off when the self-test is
complete. (The LEDs are shown in Figure 2-4.)
4. Turn on the PC, cable or DSL modem and/or Router.
TheAdapter’s hardware installation is now complete.
Figure 3-2
Connecting Your Hardware Together and Booting Up
Chapter 3:Connect the USB VPN &

The Adapter’s setup consists of more than simply plugging hardware together.
You will have to configure your networked PC to accept the IP address that the
Adapter assigns to your computer, and you will also have to configure the
Adapter with setting(s) provided by your Internet Service Provider (ISP).
Contact your ISP for the correct settings if you do not have the information
available.
Once you have the setup information you need for your specific type of Internet
connection, you can begin installation and setup of the Adapter.

Chapter 5: Configure TCP/IP
The instructions in this chapter will help you configure your computer to be
able to communicate with the Adapter using TCP/IP.
To do this, you need to configure your PC’s network settings to obtain an IP (or
TCP/IP) address automatically (called DHCP). Computers use IP addresses to
communicate with each other across a network or the Internet.
Find out which operating system your computer is running, such as Windows
XP, 2000, Millennium, or 98. You will need to know which operating system
your computer is running. You can find out by clicking the Start button and
then going to the Settings option. Then click Control Panel, and then double-
click the System icon. If your Start menu doesn’t have a Settings option, you’re
running Windows XP. Click the Cancel button when done.
You may need to do this for each computer that you are connecting to the
Router.
The next few pages tell you, step by step, how to configure your network set-
tings based on the type of Windows operating system you are using. Make sure
that an adapter has been successfully installed in each PC you will configure.
Once you’ve configured your computers, continue to “Chapter 6: Configure
the Adapter.”
