A VPN (virtual private network) provides a secure, virtual
tunnel between two network devices. A common use of a
VPN is to allow a remote user to connect
to an organisation's network with priviledges associated with the "inside"
of the network, rather than being treated as "outside" the
network (and therefore the firewall.)
