We are communicating the Cisco ASA 5505 with our own Radius server for Authorization and Accounting purposes.
We have been able to assign the IP address to the VPN client through Radius Authentication request and are correctly receiving Accounting Start and Stop signals.
But we DO NEED Acocunting Interim updates, triggered by timeout or volume (every x seconds or every n Kbytes, for instance).
The configuration screens suggest that Radius interim updates are possible (see figure below), but we have not been received any.
