I am using Mikrotik Routerboard 1200 , I am trying to use the hotspot system that is built in , I tested hotspot with http://www.hotspotsystem.com and it worked perfectly using their guide.

I am trying now to use this hotspot system with our radius server, we were using this radius server with dd-wrt and now we want to use it with Mikrotik.

I think the steps will be the same for configuring the hotspot, but what about the login page?? What are the steps that Mikrotik take to verify the login process with an external radius server?

I use FreeRADIUS with good results. The login page is on the hotspot router in my case. The setup is simple on the hotspot end. If you have used the login with local database, it will not seem any different. I use "login-by=http-chap" in the hotspot profile. That keeps the password encrypted.

Add the router ip and radius secret in your radius client database. Then I use:

You cannot use hotspotsystem with external radius servers.

Hotspotsystem provides a complete, cloud-based billing and management solution, including hosted radius servers.

You can configure mirktoik with an external radius server, but hotspotsystem won't add users to an external radius server, so users wont be able to log in.

What is the point of using your own radius server?
