Hi,
I think you can only apply a time range when the VPN Client connection for a user will be available (for example the time range mentioned 23:00 to 7:00.
And also the one you mentioned which is the maximum connection time (and idle time) for a user.
There should also be possible to build access rules on the firewall that are time range based. Basically traffic would be allowed only during some time frame.
But from what I gather you would want to limit the total connection time between 23:00 to 7:00 to 34 minutes (NOT 34min max for each connection the user takes during that time range)
