Chapter 3: Connecting the
Cable/DSL VPN Router to Your
Network
Overview
Unlike a simple hub or switch, the setup of the EtherFast
Router consists of more than simply plugging everything together. Because the
Router acts as a DHCP server, you will have to set some values within the
Router, and also configure your networked PCs to accept the IP Addresses the
Router chooses to assign them.
You may need the following values from your ISP in order to install the
EtherFast
®
Cable/DSL VPN Router:
• Your broadband-configured PC's fixed Internet IP Address (if applicable)
• Your broadband-configured PC's Computer Name and Workgroup Name
• Your Subnet Mask (if applicable)
• Your Default Gateway (if applicable)
• Your Primary DNS IP Address (if applicable)
Whoever installed your broadband access should have left this information
with you. If not, call your ISP and they will be able to supply you with it.
About Static & Dynamic IP Addresses
Static IP Addresses A static IP address is an IP address permanently assigned
to a computer in a TCP/IP network. Static IP addresses are usually assigned to
networked devices which are consistently accessed by multiple users, such as
Server PCs, or printers. If you are using the Router to share your cable or DSL
Internet connection, contact your ISP to see if they have assigned your home a
static IP address. You will need that address during the Router's configuration.
found in network devices such as Routers.
Dynamic IP Addresses A dynamic IP address is an IP address that is automatically
assigned to a client station (computer, printer, etc.) in a TCP/IP network. Dynamic
IP addresses are typically assigned by a DHCP server, which can be a computer
on the network or another piece of hardware, such as the Router. A dynamic IP
address may change every time your computer connects to the network.

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.
Connecting Everything Together & Booting Up
Once you are sure that you have the above values on hand, you can begin the
installation and setup of the EtherFast
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 Cable/DSL 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 the How to Ping Your ISP's E-mail and Web Addresses
section in the Appendix.
1. Power everything down, including your PCs, your Cable or DSL modem
and the Router.
2. Connect a network cable from one of your PCs' Ethernet ports to one of the
LAN ports on the back of the Router. 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 3-1 when setting the
Crossover Switch.
