OnCell G3100 Series Understanding and Configuring a VPN
What Are VPNs?
Computers that are part of a 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.
