  Then your NAS is garbage.  Throw it away and buy one that follows the RADIUS protocol.

  The NAS should also send packets when it reboots.  This tells the RADIUS server that it has rebooted.  Which tells the RADIUS server to clear all active sessions.

  The NAS isn't sending those packets, so the RADIUS server has no idea that it rebooted.

  Which will be ignored by most NASes.  The minimum value is generally 5 minutes, or 300.

  No.  You don't get packets from the NAS when the NAS is off-line or not connected.

  You have access to the SQL server.  Edit the SQL database.
