Virtual Private Network

Computers that are part of a virtual private network (VPN) use a second, “virtual” IP address to connect to the

Internet. Instead of running across a single private network, some of the links between nodes that are part of

a VPN use open network connections or virtual circuits on a larger network, such as the Internet. With the help

of VPNs, cellular devices acting as a VPN client can initiate a connection with a VPN server. Once the connection

is established, cellular devices can communicate with other network devices on the same private network.

The following figure shows a network example.
