What is the VPN function of the MachineLink 4G?

A virtual private network (VPN) is a secure connection between two or more endpoints on a network.

There are two types of VPN scenarios:• Site to site VPN where data is encrypted from one VPN gateway to another over a third party network such as the internet

• Remote Access VPN where a secure connection is established between an individual computer and a VPN gateway.

The MachineLink 4G router supports the following VPN protocols:

• IPSec• OpenVPN• PPTP• GRE

IPSecIPSec is a VPN protocol operating at the internet protocol (IP) layer of the internet protocol suite.

It can be used to secure data flow in the following configurations:• Host-to-host• Network-to-network• Network-to-host

OpenVPNOpenVPN is an open source virtual private network program for creating point-to-point or server-to-multi-client encrypted tunnels between host computers.

It can traverse network address translation (NAT) and firewalls and provides 3 methods of authentication:

• Certificate• Pre-shared key• Username/password

PPTP-Client

GRE

The Point-to-Point Tunnelling Protocol (PPTP) is a method for implementing virtual private networks using a TCP and GRE tunnel to encapsulate PPP packets. PPTP operates on Layer 2 of the OSI model and is included on Windows computers.

The Generic Route Encapsulation (GRE) protocol is used in addition to Point-to-Point Tunnelling Protocol (PPTP) to create VPNs (virtual private networks) between clients and servers or between clients only. Once a PPTP control session establishes the VPN tunnel GRE is used to encapsulate the data or payload.

What can you do with VPNs?With respect to the MachineLink 4G router, the benefits of using a VPN include:

• Security – All traffic in and out of the router is encrypted (except when using GRE) ensuring the integrity of your network.

• Common network – the devices can be placed in the same subnet meaning that they can be more easily administered.

• Anonymity – because the router is connecting to a VPN gateway, any remote connections it may make appear to come from the gateway.

• Reduce maintenance costs and time – when you have multiple routers on the same network, you can save time and money by reducing the effort required to service them.
