GRE Tunnel

GRE (Generic Routing Encapsulation RFC2784) is a solution for tunneling RFC1812 private address-space traffic over
an intermediate TCP/IP network such as the Internet. GRE tunneling does not use encryption it simply encapsulates data
and sends it over the WAN.
In the example network diagram two distant networks LAN1 and LAN2 are connected.
To create GRE tunnel the user must know the following parameters:
1. Source and destination IP addresses
2. Tunnel's local IP address
3. Distant network's IP address and Subnet mask
To create a new GRE instance, go to the GRE Tunnel tab, type in a name for your new instance in the text field
below the GRE Tunnel tab and press the "Add New" button next to it.
The newly created instance will be disabled and unconfigured. To configure it press the "Edit" button located next
to it (as seen in the example above). This action will redirect you to the instance's GRE Tunnel Configuration window.
