GRE Tunnels
GRE tunneling and GRE routing together are referred to Generic Routing Encapsulation (GRE). GRE Routing is an integral
part of GRE tunneling. First, the GRE Tunnels are created using the GRE Tunnel Configuration. Then the routes for the remote
networks that are to be routed through a tunnel need to be specified in the GRE Routes Configuration. Thus, all the traffic
destined to remote networks associated to a tunnel will get routed through that tunnel.

Tunneling allows the use of a public network to convey data on behalf of two remote private networks. It is also a way to
transform data frames to allow them to pass networks with incompatible address spaces or even incompatible protocols. If you
want to read more about how this works, see the online Help.
GRE Tunnel Configuration
Tunnel Name:
Enter a name for the new tunnel.
Local IP:
Select the local interface on which the tunnel is being created. Eventually, the packets destined for
this tunnel will be routed through it.
Note:
When adding a tunnel, use only one of the following:
Remote IP
or
FQDN
.
Remote IP:
Select the Remote IP address that marks the other end point of the tunnel (this is the one to which
the routed packets will be received).
OR
FQDN:
Enter the FQDN (Fully Qualified Domain Name) for the Remote IP, which can be either the IP
Address or an FQDN.
Add Button:
Click
the
Add
button. The defined GRE tunnel configuration is added and will display at the bottom
of the screen.
