So, my question is: how can I use Simultaneous-Use in this scenario? Should I make a script that test if the NAS is online every 10 seconds and if not list all clients connect and stop that connections? Should this work? Is there anyone with the same scenario that can share the solution for the problem?

You can use radclient to send fake accounting stop packets to clear up the stale sessions.
