Hello,<br><br>I am running a PopTop server with FreeRadius for authentification. I have configured FreeRadius to use Oracle and I can successfully authenticate the users that connect to the VPN.<br><br>My questions is how can I after a certain-period of time or after a certain condition is&nbsp; true (for example a value in the db in a table reaches 0) to disconnect a certain user ?<br><br>Reading the documentation from the site I understood that the NAS server is responsable with this. How can i then do this using PopTop &amp; FreeRadius ?<br><br>Any help or hint is appreciated !<br><br>Thank You<br><br><p>&#32;
