C-18 Preparing Your Network

202-10005-05, June 2005

Verifying the Readiness of Your Internet Account

For broadband access to the Internet, you need to contract with an Internet service provider (ISP)

for a single-user Internet access account using a cable modem or DSL modem. This modem must

be a separate physical box (not a card) and must provide an Ethernet port intended for connection

to a Network Interface Card (NIC) in a computer. Your router does not support a USB-connected

broadband modem.

For a single-user Internet account, your ISP supplies TCP/IP configuration information for one

computer. With a typical account, much of the configuration information is dynamically assigned

when your PC is first booted up while connected to the ISP, and you will not need to know that

dynamic information.

In order to share the Internet connection among several computers, your router takes the place of

the single PC, and you need to configure it with the TCP/IP information that the single PC would

normally use. When the router’s Internet port is connected to the broadband modem, the router

appears to be a single PC to the ISP. The router then allows the PCs on the local network to

masquerade as the single PC to access the Internet through the broadband modem. The method

used by the router to accomplish this is called Network Address Translation (NAT) or IP

masquerading.

Are Login Protocols Used?

Some ISPs require a special login protocol, in which you must enter a login name and password in

order to access the Internet. If you normally log in to your Internet account by running a program

such as WinPOET or EnterNet, then your account uses PPP over Ethernet (PPPoE).

When you configure your router, you need to enter your login name and password in the router’s

configuration menus. After your network and router are configured, the router will perform the

not necessary to uninstall the login program.

What Is Your Configuration Information?

More and more, ISPs are dynamically assigning configuration information. However, if your ISP

does not dynamically assign configuration information but instead used fixed configurations, your

ISP should have given you the following basic information for your account:

1 2 ... 179 180 181 182 183 184 185 186 187 188 189 ... 235 236
