Introduction

PPPoE (Point-to-Point Protocol over Ethernet) is a specification for connecting multiple computer users on an Ethernet local area network to a remote site through common customer premises equipment, which is the telephone company's term for a modem and similar devices. PPPoE can be used to have an office or building-full of users share a common Digital Subscriber Line (DSL), cable modem, or wireless connection to the Internet. PPPoE combines the Point-to-Point Protocol (PPP), commonly used in dialup connections, with the Ethernet protocol, which supports multiple users in a local area network. The PPP protocol information is encapsulated within an Ethernet frame.


This article provides a guide on how to configure PPPoE server on Mikrotik and how to connect RUTX router, Windows computer to it.

Prerequisites

  • Any RUTXxx device.
  • One MikroTik router (this guide was created by using MikroTik RB750Gr3).
  • Windows 10 computer. (Mikrotik and RUTXxx configuration will also work with other OS platforms)
  • WinBox application (it is used to access the MikroTik router).
