MikroTik PPPoE Server is popularly used in ISP Companies to maintain user connection. Along with MikroTik PPPoE Service it is a better idea to make a prepaid billing system with Radius Server. MikroTik User Manager Radius Server is a user authentication and accounting application that gives the ISP Company ability to manage PPPoE user’s connection with proper bandwidth management as well as their prepaid billing system with scratch card. So, any ISP Company can turn a smart network system with MikroTik PPPoE Service and User Manager prepaid billing system. This article is designed to show how to setup an ISP network with MikroTik PPPoE Server and User Manager prepaid billing system.

Purpose of this Article

The purpose of this article is to setup an ISP network which will have

• MikroTik PPPoE Server for user connection.
• MikroTik User Manager Radius Server for user authentication and bandwidth package management.
• User Manager prepaid billing system with scratch card.

Network Diagram

For the configuration of this article I am going to establish a network like below network diagram.

This is a simple and basic network diagram. In a real situation, your network may be larger than this network but the basic diagram will remain same. In this network, the WAN Distribution Switch is connected to internet gateway. MikroTik Router’s WAN interface, MikroTik User Manager Radius Server and our Admin PC is also connected to this WAN Distribution Switch. PPPoE users will be connected to core MikroTik Router through LAN Switch and will get internet access.

Core Devices and IP Information

To setup an ISP network according to above network diagram, I have installed and completed initial configuration of MikroTik User Manager Radius Server Package in a dedicated physical server where MikroTik RouterOS is running. I have also a physical MikroTik RouterOS (MikroTik RouterBOARD 1100AHX2) which is the core router in this network. IP information that I am using for this network configuration are given below.

• Radius Server IP: 192.168.110.10/28
• MikroTik RouterOS WAN IP: 192.168.110.2/28
• Admin PC IP: 192.168.110.5/28
• LAN IP Blocks: 192.168.10.0/24, 192.168.20.0/24 and 192.168.30.0/24
• PPPoE Server IP: 192.168.10.1

This IP information is just for my RND purpose. Change this information according to your network requirements.
