I have setup a new Microsoft proxy server 2.0 as a gateway for a workgroup to access the Internet via modem connection. It works well, such as to cache URLs, automatically dial the ISP ...
The problem is, it seems the RAS connection cannot be disconnected automatically when there is no user to access the net. Of course, I noticed there is an option in Modem properties, Disconnect a call if idle for more than n minutes, but it looks the option has no any effect. I also have tried to use Dial-up Networking to manually call an ISP, then do nothing to wait for the line disconnect, still with no luck. :-( So, I have to hang up the RAS connection manually every time the clients have no interest on the net. :-((
Also, the Dialing Hour Schedule has no any effects to control client's access to the net. Why?
