Vrde property "TCP/Ports" is ignored in IPV6

[Nico Orrù]

I have multiple VMs on a host, I need a separate VNC port for the consoles.

Unfortunately, I can't set TCP ports for ipv6, as the settings appears to be ignored.

$ sudo su - vbox -c 'VBoxManage modifyvm test_machine_1 --vrdeproperty "TCP/Address=0.0.0.0"'
$ sudo su - vbox -c 'VBoxManage modifyvm test_machine_1 --vrdeproperty "TCP/Ports=5901"'
$ sudo systemctl start vboxvmservice@test_machine_1.service
$ sudo systemctl status vboxvmservice@test_machine_1.service

I have tried to change `VNCPort4` `VNCPort6` `TCP6/Ports` properties to no avail.

Can you please tell me if:
1) it works with latest vbox6 version
2) it is reproducible with the upstream deb file
