I too use VyprVPN courtesy of Giganews, and I was totally unaware that there was such a difference in the setup. I too would have fallen into the same trap, and would have suffered the same angst - especially since this particular factoid is not reflected in the topic title.
A humble suggestion, please, please, pretty-please?
Please update your configuration document(s) to show this difference in the configuration for Giganews customers. This will, very likely, save everyone a lot of angst, headaches, ill will, and forum head-banging.
