Freeradius and Cisco ASA => Accounting and IP Static

Hi I use FreeRadius for authenticate my IPSEC VPN User on a Cisco ASA. I search to know if it's possible: - Get Accounting for know: Login connection Start Login stop and time connected and if possible the number of Ko used - Use FreeRadius for IP Pool: Actually, it's the Asa that attribute IP Adresse with a IP Pool Do you know if it's possible that it's Freeradius sent the IP Adresse for use IP Static based on the login ? I Use a Perl Script in auth Thanks jerome
