I wasn't really sure where to post this one, but captive portal seemed like a good place since it is related to the functionality I'm seeking.
Would it be possible to get untangle to send Accounting Updates back to the RADIUS server with the traffic usage updates.
This behaviour allows the RADIUS server to record usage for each users and let the NAS (Untangle) know if a specific user has reached its transfer limit and needs to be disconnected.
It is implemented in PFSense and many other platforms, and it would be a great asset for Untangle expanding its presence among ISPs and WISPs.
Please let me know.
