GRE Tunnel
Generic Routing Encapsulation (GRE) is one of the available tunneling mechanisms which uses an IP as the

To create and configure a secure GRE tunnel, follow these steps:
Step 1 Click VPN > GRE tunnel.
Step 2 Click Add to add a new configuration or Edit or Delete to edit or delete an existing one.
Step 3 In the Add/ Edit a GRE tunnel section, configure the following:
Enter the name of the interface to connect to tunnel.Interface Name
Check to enable the interface.Enable
Select the tunnel source from the drop-down list.Tunnel Source
Enter the tunnel destination (Static IP or FQDN).Tunnel Destination
Enter the IP address of the GRE tunnel which carries the transport protocol.IP Address of GRE tunnel
Enter the subnet mask of the GRE tunnel.Subnet Mask
Enter the maximum transmission unit (MTU).MTU
