Radius accounting commands

Hi, I want to run Mikrotik router as NAS, but I seem to have a problem with Radius configuration.

Seems the problem is in the accounting commands that the router sends to Radius server. Router sends ACCOUNTING_ON (and probably ACCOUNTING OFF) instead of ACCOUNTING_START / ACCOUNTING STOP.

Radius log:
unsupported acct status received=

Any way I can fix that? Any suggestions?

what RADIUS do you use? FreeRadius works fine

Microsoft IAS (Internet Authentication Service) with proprietary billing solution.. Is there a way to change command that is being sent to Radius server (manually modifing some file would not be a problem).

proprietary? so change your packet handlers in RADIUS

I figured it out. It was configuration issue. Now works as it should. Thank you for your attention.
