Regarding Remote Authentication for 3G connected Hotspots through Mikrotik

Hello there,

Can anyone help me out with the following setup??

3G dongle → connected to WiFi Router

the authentication for the users connecting to the router should come from a remote Mikrotek server with a static IP.

Process to be achieved:

User → connecting to WiFi router → Authentication request send → Mikrotek Server

Mikrotek Server → Authenticate if user in Database or else request dropped → User connected to WiFi.

the router’s Uplink is provided by 3G network.

You need to setup a radius server or usermanager

Just need to setup a hotspot in your mikrotik server.
User>hotspot>auth>internet
