Defining tunnels to your device
Setting up Generic Routing Encapsulation (GRE) tunnels
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.
also a way to transform data frames to allow them to pass networks with incompatible address spaces or even
incompatible protocols.
Generic Routing Encapsulation (GRE) is a tunneling mechanism that uses IP as the transport protocol and can
be used for carrying many different passenger protocols. The tunnels behave as virtual point‐to‐point links
that have two endpoints identified by the tunnel source and tunnel destination addresses at each endpoint.

Configuring a GRE tunnel involves creating a tunnel interface, which is a logical interface, then configuring the
tunnel endpoints for the tunnel interface.
tunnel endpoints for the tunnel interface.
To set up GRE tunnels:
1. From Tunnels, select GRE Tunnels. The Tunnels: GRE Tunnels pane opens.
2. From the Tunnels:GRE Tunnels pane, click Add Tunnel.
A series of wizard panels helps you configure the connection.
3. In the Tunnel Name field, enter a name for the new tunnel.
4. In the description area, type a description that helps you further identify the tunnel. Click Next.
5. In the next wizard pane:
In the Remote WAN IP field, type the IP address of the gateway to which you want to connect.
(Optional) From the Saved Network drop‐down list, select the network that is to be routed through
the tunnel. To select a local interface: Select the local interface on which the tunnel is being created.
Eventually, the packets destined for this tunnel will be routed through it

If you are not using a saved network, in the Network Mask field, type the mask of the network.
Click Add Route. The defined GRE tunnel configuration is added and appears in the Network Routes
