Therouter supports PPPoE (Point-to-Point Protocol over Ethernet).PPPoE is an IETF Draft standard (RFC 2516) specifying how apersonal computer (PC) interacts with a broadband modem (forexample, DSL, cable, or wireless) connection. Operationally, PPPoEsaves significant effort for both the end user and ISP or carrier, as itrequires no specific configuration of the broadband modem at thecustomer site. By implementing PPPoE directly on the router ratherthan individual computers, the computers on the LAN do not needPPPoE software installed, since the router does that part of the task.Further, with NAT, all of the computers on the LAN have access.Service Name Type the PPPoE service name provided to you. PPPoE uses aservice name to identify and reach the PPPoE server.User Name Type the username given to you by your ISP.Password Type the password associated with the username.Nailed UpConnectionSelect Nailed Up Connection if you do not want the connection totime out.Idle Timeout This value specifies the time in seconds that elapses before the routerautomatically disconnects from the PPPoE server.Apply Click Apply to save your changes to the Business Secure Router.Reset Click Reset to begin configuring this screen afresh.
