Well, the web access part is likely simple if you have a web
dev in house, as the client properties of the browsing client
will give you pretty much all you would need to tell if they
are on local network, vpn'd in, or using the public interface
on internet, and the server-side could then tune what is given
in the browser rendering as appropriate.
For the other access it sounded as if you need to distinguish
between only locally attached or vpn'd in. If you could isolate
the shares on to different servers and then for example use
IPsec on the server with the sensitive shares that should not
be available when vpn'd in so that server will not speack with
the IPs your vpn gives out . . .
There are likely other, and possibly more simple ways, but
given your sketch of requirements these are what first came
to mind. The alternatives will also vary based on info you
did not provide, such as what vpn solution is in use, do you
use IAS for auth, etc..
