Hotspot is one of the most popular services in MikroTik Router. It is popularly used in Hotel and Restaurant, Railway Station or Airport, School or University Campus and so on. Even ISP network and office network also use MikroTik Hotspot for authenticating network clients/users. Hotspot user can be managed with Hotspot’s local user database or with a Radius Server. Radius Server gives facility to manage Hotspot user’s bandwidth and accounting easily and centrally. So, Hotspot setup with Radius Server can be a wise decision. MikroTik User Manager Radius Server is a centralized user authentication and accounting application that gives the ISP or network administrator ability to manage PPP users, Hotspot users and login users from one server throughout a large network. It also has an awesome user bandwidth package management feature. So, network configuration with MikroTik Hotspot and MikroTik User Manager Radius Server will be a smart decision. For this, in this article I will discuss how to configure a smart network with MikroTik Hotspot and MikroTik User Manager Radius Server.

Article Purpose

The purpose of this article is to get ability to configure a Hotel and Restaurant network, Railway Station or Airport network, School or University Campus network, ISP network or Office network with MikroTik Hotspot and MikroTik User Manager Radius Server.

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 might 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 (NAS) WAN interface and MikroTik User Manager Radius Server is connected to this WAN Distribution Switch. Hotspot users will be connected to NAS Router through LAN Switch and will get internet access.

Core Devices and IP Information

To setup a Hotspot 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 NAS (Network Access Server) RouterOS 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 (NAS) WAN IP: 192.168.110.2/28
• LAN IP Block: 192.168.10.0/24
• Hotspot Server IP: 192.168.10.1

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