I'm aware of that option (as well as using the -b option) but in our particular case we have several systems under test with different configurations and we want to use this virtual port only. Which seems to be a perfect use case for white listing rather than black listing or modifying the system configuration. As far as I remember this option was available in previous versions. Thanks, Nico.
