I have a basic PPTP/L2TP setup that uses a remote freeradius server with mysql. Issue is that when a user gets connected to the vpn and as long as the user stays connected (could be hours), no accounting data is updated (bandwidth usage). Only on disconnect does it update the actual bandwidth usage etc.
I have tried setting Acct-Interim-Interval = 30 in the radreply table but still no luck. Is there something i am missing? Any help is appreciated .. thanks.
