Hi Mohamad, Set reply value of 1g manually for user and see if it disconnect on usage of 1g in mikrotik nas before diving into freeradius configuration details. Once you sure that your nas is doing what it meant to do then you can start digging into FR config.

I use the Mikrotik-Total-Limit in my sqlcounter and add this counter name on the radcheck table for my users so when my users hit the 1G bandwith (1 week etc.) the connections are not droped...!!! But when the users disconnect the pppoe connection and try again to connect get the access denied message. I like to dissconnect the pppoe connection when hit 1G. Please advise me how to solve this issue. Thank you sqlcounter sample_Limit{ counter-name = Mikrotik-Total-Limit check-name = Mikrotik-Total-Limit reply-name = Mikrotik-Total-Limit sqlmod-inst = sql key = User-Name reset = never query = "SELECT ((SUM(AcctInputOctets)+SUM(AcctOutputOctets))) FROM radacct WHERE UserName='%{%k}'" } sample_Limit{ reject = 1 } if(reject){ update reply { Reply-Message := "You have reached your bandwidth limit" } reject } - List info/subscribe/unsubscribe?
