Use a commonly unblocked port for the Console VNC access
I know this is not an easy thing to just suggest, but it would be handy if the VNC Console used a port such as 443, for when people are on a library network, uni network, etc, and whatever port the VNC currently uses is blocked :)
The console service is provided by the hypervisor and not the droplet itself. As there are multiple droplets on each hypervisor node, each requires it's own port to provide the service. Currently this means that multiple ports are used so it is unfortunately not as simple as just setting a commonly unblocked port.
