I specifically don't want the internal to work as a forwarder. We are
only allowing those users with "Internet Access", to have the ISP DSN's
in their setup, everyone else should not be able to see them.
This is a rather dumb way of stopping unauthorised users accessing the
internet, I know, but at present its the only method we have
