Mikrotik - Radius avaliar

We must instruct the wireless interface to use radius authentication and accounting, and we must tell it where to find the radius server (the IP address below). The Radius server and clients (the Mikrotik boxes) need a common secret, used to hash information in either direction. I enabled the incoming radius port, meaning that the radius server can contact the client as well. Normally the client initiates all exchanges.
