How PPPoE works
The PPPoE driver makes the Ethernet appear as a serial link to the PC and the PC
runs PPP over the Ethernet, while the modem bridges the Ethernet frames to the
Access Concentrator (AC). Between the AC and an ISP, the AC acts as an L2TP
(Layer 2 Tunneling Protocol) LAC (L2TP Access Concentrator) and tunnels the
PPP frames to the ISP. The L2TP tunnel is capable of carrying multiple PPP
sessions.
With PPPoE, the VC (Virtual Circuit) is equivalent to the dial-up connection and
runs between the modem and the AC, as opposed to all the way to the ISP.
However, the PPP negotiation is between the PC and the ISP.
Business Secure Router as a PPPoE client
When using the Business Secure Router as a PPPoE client, the PCs on the LAN
see only the Ethernet and are not aware of the PPPoE. This alleviates the
administrator from having to manage the PPPoE clients on the individual PCs.
