Joe, There are lot of issues here. One thing to consider is that it is not a good policy to "cut off" the client ADSL at 0:00hs... they may complain for that policy ! You may just let him close the session and then, with the accounting stop ticket you may account part of it on the past month and the rest the current month. :) You may also set a maximum connection time for one session (some ISP do this also)... say for example 12 hours... so each 12 hours the RAS closes the connection (the thig is that this timer is for each connection, so you do not close all the connections at same time)... you may do this using standar radius attribute 27 (Session-Timeout) by modifying this attribute in the access-accept response from the radius to the RAS. You may also use interims... but Im not sure if you have traffic information on this... This are some ideas... there are a lot more... Hope it help, Nicolas.
