Reference Manual for the Model DG814 DSL Modem Internet Gateway
For a
In order to share the Internet connection among several computers, your gateway 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 gateway’s ADSL port is connected, the gateway appears to be a single PC to the ISP. The gateway 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 gateway to accomplish this is called Network Address Translation (NAT) or IP masquerading.
Login Protocols
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 gateway, you will need to enter your login name and password in the gateway’s configuration menus. After your network and gateway are configured, the gateway 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.
Account Information
Unless these items are dynamically assigned by the ISP, your ISP should give you the following basic information for your account:
•An IP address and subnet mask
•A gateway IP address, which is the address of the ISP’s router
•One or more domain name server (DNS) IP addresses
•Host name and domain suffix
For example, your account’s full server names may look like this:
mail.xxx.yyy.com
In this example, the domain suffix is xxx.yyy.com.
