You should really do this. I tried to install on friend's QNAP and it will never work.
In recent version of OS there is no setting to change port of Virtualization Station.
I think my friend uses latest beta version of OS and he told me that setting is gone
I updated QTS to v4.4.1.0998 (beta) and Virtualization Station to v3.1.834
Still see the port setting under Preferences > Ports
