Seems like QuickVPN only establishes the connection within Wine, and
that's why you don't see the connection info within Linux. After
establishing the connection, can you try launching a browser within
wine? If this works, it looks like you need to find a way to bridge the
connection from Wine to the parent OS. I'm afraid I don't have any more
details than that at the moment.
