IPSec VPN Between Two Networks

Users can connect from an internal network at one location to an
internal network at another location via the Internet.
Communication between the two networks takes place in an
encrypted VPN tunnel that connects two DFL-1100 units across
the Internet. Users of the internal networks are not aware that
when they connect to a computer on the other network, the
connection runs across the Internet. The connections can be
made to the internal LAN connections or to the DMZ connections.
