Maybe. Depends on what kind of VPN technology you're using, and how
you set it up.

If you're running a VPN client (PPTP/L2TP, SSL VPN, IPSec (including
DirectAccess), etc.) on a machine in network A to connect to network
B, then it's unlikely the other machines in network A will be visible
to the machines on network B - though it might be possible if you have
turned on network sharing (ICS, IIRC), on the machine in network A - I
haven't tried that, though. But f ICS is turned on, then you've
essentially turned the machine in network A into a router, and more.

I'm sure that there are some other circumstances where the 'A'
machines could be visible to the 'B' machines, but I don't consider
them very likely.

That's part of the reason why it's called a VPN.

  Maybe.

  If you're asking the question, very probabbly.

  A VPN is just a network connection.  There is nothing special about
it unless something is done to make it special.  Think of it as an
Ethernet cable.

  Incorrect.  See above.
