Setting up a PPPoE between RUTX and Mikrotik device

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.

• One MikroTik router (this guide was created by using MikroTik RB750Gr3).
