PPPoE (Point-to-Point Protocol over Ethernet) is a network protocol for encapsulating PPP frames in Ethernet frames. Just as pptp, it allows a subscriber accessing the network by using authorization, encryption, compression etc. This is mostly used by ADSL service providers.
This article talks about configuring and installing PPPoE on Linux.
For providing access via PPPoE it is required a PPPoE network access server (NAS) and a subscriber’s unit (PPPoE client). In this guide as a PPPoE network access server it is used a freeware packet rp-pppoe working in the kernel mode on Gentoo Linux.
Instructions includes step-by-step MS-Windows client configuration.
