Configure OpenVPN on Qnap NAS

Job ID: 30953174

Budget: £250 – £750 GBP

Need to Configure OpenVPN on QNAP TS-453A, so that multiple users can access NAS CAD/CAM/AutoCAD files simultaneously from their home using VPN. Basically It should complain that the file is in use, if any other user had it already opened and working. Team Size/AutoCAD users are 4.
