Need to limit traffic throughput to a certain amount of data, then stop

[silveriochiaradia]

I have a situation where there is a need to limit the traffic to a certain amount of data, lets say 5GB. When the user downloads 5GB of data by any means, their access should be blocked.

I went to lots o hints, but still dont know how to do this with pfSense (Good package, btw!)  ;D

I would appreciate anyone who can help me on this.
