Hello, We currently authenticate FTTH Subscribers with FreeRadius. It works like that : Subscriber --> DHCP Request --> NAS that does DHCP to Radius --> Access Request --> Proxy Freeradius --> ISP Home server In the Authentication/Autorization phases, The Freeradius Proxy gets the ADSL-Agent-Circuit-Id Attribute from the Request and ask a SQL database to provide the information to who it should proxy (Proxy-To-Realm), then in Preproxy phase, it does some Attribute change and send the request to the correct home server. This has been working very well since many years now. (eg Authentication Proxification based on SQL) Recently, We've been ask by ISP to do the same for accounting. So we manage to tell our NAS to speak Accounting (based on DHCP), and the Proxy Freeradius does receive Accounting. But for now I've not been able to proxy this accounting using the same way We do it for Authentication requets. When we use SQL module, in accounting part, it does insert accounting information into the SQL, but does not request information from the database. I know that I could change this SQL request in sql.conf (eg SELECT instead of INSERT), but will it work ? Thanks Thomas
