I am trying to implement billing using MikroTik and RADIUS server. Using RADIUS protocol I am sending Mikrotik-Total-Limit attribute (in Access-Accept packet) so that NAS (MikroTik) will know how much bytes the client is allowed to send and receive. But for some reason, MikroTik does not send Accounting-Stop packet when the number of bytes transmitted and received reaches the threshold. Can someone help me out with this problem? What am I doing wrong?
