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 firewall 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 firewall 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 firewall’s Internet port is connected to the broadband modem, the firewall 
appears to be a single PC to the ISP. The firewall 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 firewall 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 will need to enter your login name and password in the 
router’s configuration menus. After your network and firewall are configured, the firewall will 
perform the login task when needed, and you will no longer need to run the login program from 
your PC. It is 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:
