Linux Tutorial: Accessing the Internet

6. xDSL Configuration

There are two main types of xDSL configuration in use and most ISPs use either one of these:

• DHCP over Ethernet
• PPoE over Ethernet

Usually if you given a login id and password for your broadband xDSL connection then you should be using the PPoE configuration.

DHCP over Ethernet

For this configuration, what is needed is just to obtain the IP configuration parameters using DHCP (Dynamic Host Configuration Protocol). To set up your xDSL customer premises equipment to perform this, the "Internet Configuration Wizard" tool from the Main Menu may be used:

Main Menu --> System Tools --> Internet Configuration Wizard

You will be prompted for the root password as this is an attempt to change the system settings and so only the system administrator is allowed to perform this. Enter the root password and the Internet configuration wizard main screen will be displayed as described in the section on dial-up modem configuration.

1. Select Ethernet connection in the select device type screen and click on the Forward button. A screen showing the detected Ethernet card(s) on your system is displayed.

2. In the Configure Network Settings screen., click the button marked "Automatically obtain IP address settings with:" and ensure that "dhcp" is selected from the pull-down selection. Also check the box "Automatically obtain DNS information from provider". Click on the Forward button.
