Cable/DSL VPN Router with 4-Port 10/100 Switch
4. Connect the network cable from your cable or DSL
modem to the WAN port on the Router’s rear panel, as
shown in Figure 4-3. This is the only port that will
work for your modem connection.
5. Connect the power adapter to the Power port on the
Router’s rear panel, as shown in Figure 4-4, and then plug
the power adapter into a power outlet.
• The Power LED on the front panel will light up green as
soon as the power adapter is connected properly.
• The Diag LED will light up red for a few seconds when
the Router goes through its self-diagnostic test. This
LED will turn off when the self-test is complete.
6. Turn on the cable or DSL modem.
7. Press the Reset button on the Router’s front panel with a paper clip or a pen-
cil. Hold the button in until the Diag LED lights up and then turns off. This
will restore the Router’s factory default settings.
The Hardware Installation is complete.

Note: The diagram above is for reference purposes only. Every
network is different. If you do not make a connection to a hub or
switch by using the settings above, change the position of the
Crossover Switch.

Important: You should always plug the Router into a power strip
with surge protection.
DHCP (Dynamic Host Configuration Protocol)
DHCP is software that automati-
cally assigns IP addresses to client stations logging onto a TCP/IP network.
DHCP eliminates having to manually assign permanent IP addresses to every
device on your network. DHCP software typically runs in servers and is also
found in network devices such as routers.
Once you are sure that you have the above values on hand, you can begin the
installation and setup of the VPN Router.
1. Power everything down, including your PCs, your Cable or DSL modem
and the Router.
2. Connect a network cable from one
of the LAN ports on the back of
the Router to one of your PCs’
Ethernet ports, as shown in Figure
4-1. Do the same with all the PCs
you wish to connect to the Router.
3. If you are using Port 4 to connect to a PC, set the Crossover Switch to
straight-through mode (
II
). If you are connecting the Router to a hub or
switch, please refer to the chart shown in Figure 4-2 when setting the
Crossover Switch.
Note: Some ISPs—most notably some cable providers—configure
their networks so that you do not have to enter a full Internet address
into your web browser or e-mail application to reach your home page
or receive your e-mail. If your Internet home page address is some-
thing very simple, such as “www”, rather than “www.linksys.com”,
or your e-mail server’s address is something similar to “e-mail” or
“pop3”, rather than “pop.mail.linksys.com”, you won’t be able to
properly configure the VPN Router until you determine the actual
Internet addresses of your Web and e-mail connections.
You must obtain this information prior to connecting the Router to
your network. You can obtain this information by contacting your ISP,
or turn to “Appendix E: How to Ping Your ISP’s E-mail and Web
Addresses.”
