But, we were talking about end-user connected into the inside network using
a VPN. That user needs to have pretty much unfettered access to the
business parts of your internal network. (Okay, mission critical stuff
should be seperately firewalled, but MS makes that hard enough, due to
things like Active Directory, where everything needs to talk to everything).
