How PPPoE Works
The PPPoE driver makes the Ethernet appear as a serial link to the PC and the PC runs PPP
over it, while the modem bridges the Ethernet frames to the Access Concentrator (AC). Between
the AC and an ISP, the AC is acting as a 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 is 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.
WR1500 Wireless Router as a PPPoE Client
When using the WR1500 Wireless Router as a PPPoE client, the PCs on the LAN see only
Ethernet and are not aware of PPPoE. This alleviates the administrator from having to manage
the PPPoE clients on the individual PCs.
