Configuration on Routing and Remote Access

  1. Click Start, point to Administrative Tools, and then click Routing and Remote Access


  2. From the left pane, click on the Remote Access Policies node.



  3. Right click on ISA Server Default Policy and click on Properties


  4. The ISA Server Default Policy Properties page will open, click on the Edit Profile button


  5. The Edit Dial-in Profile page will open, under the Dial-in Constraints, we have two options



    Minutes server can remain idle before it is disconnected (Idle-Timeout )

    Minutes client can be connected (Session-Timeout )

    The first option is as saying to Disconnect if idle for the specified number of minutes, whereas the second option is as saying to restrict maximum session to the specified number of minutes

    We do not want to kick out a VPN Client if he is working and not idle, what I want to enable is the first option, if any VPN client becomes idle for more than lets say 30 minutes, then I don't want him to stay connected to my Network, in this way, I made more resources available for other VPN Clients, for example if I have a limited number of IP Addresses that I can distribute to VPN Clients, then if these idle users kept connected to my Network, and the Max number of VPN Clients has been reached, then other users won't be able to Dial-in unless these Idle users get disconnected so that we have more free IPs to others.

  6. So Enable the option Minutes server can remain idle before it is disconnected (Idle-Timeout ) and set the number of minutes you want that suites your needs. Then click OK > OK > OK and we are done.


Conclusion
In this article we learned how to disconnect Dialed-in VPN Clients that their sessions are idle for a specific amount of time.
