Whatever you may say, the main server will have only 1 or 2 ports at the most. And that port bandwidth is shared among the VPS. So it is shared.

I wont post here again, but the truth is that a main server can have a port which is ultimately shared among all VPS containers.

And coming to the point, I would not are much for bandwidth as I do not do all these "warez stuff" and so I dont need to leech or anything that needs high bandwidth.
