Modifying a PPPoE modem

Double-click on the PPPoE interface that you wish to modify - its control panel will open.

“General configuration” tab


ON / OFF Set the switch to ON / OFF to enable/disable the modem.
By disabling an interface, it becomes unusable. You can disable modems that are not active, but which you intend to use in the future. An interface which has been disabled because it is not in use is an example of an additional security measure against intrusions.

Service Type of PPPoE service used. This option allows distinguishing between several ADSL modems. Leave this field empty by default.
