What is a Virtual Private Network (VPN)?
A VPN is the extension of a private network across public or shared networks such as the
Internet. A VPN allows data to be sent between two computers across the Internet in a manner
that emulates a point-to-point private link.
Sample VPN Tunnel Setup
This example will demonstrate how to create a Virtual private Network (VPN) between two
remote locations through the Internet. The VPN policy will use 3DES IPSec to securely
send/receive encrypted data over the Internet. When the VPN tunnel is enabled, the two offices
will virtually appear to be on the same local network.
This example will consist of two DI-804V VPN Routers with a simple setup. The two remote
offices in this example will be known as Office A and Office B. Both VPN Routers must
already be set up and able to access each other. This is only an example, your setup will vary
using the WAN IP address provided by your ISP.
Please note the differences in the IP addresses for each office.
