Normally we configure IPsec for LAN-to-LAN communication, also known as split-tunnel VPN, when only specific hosts or subnets should be reachable via a VPN tunnel. However, we may also take a different approach and configure a VPN tunnel using the full tunnel method. This means that any non-directly connected network (i.e. lan interface) will be reachable only via IPsec tunnel and not via the typical default route.

'''RUT''' – '''RUT''' will act as a '''hub'''. A hub is a server, to which our spoke will be connected (IPsec responder). It will be our "default gateway" for the spoke device. RUT has a LAN subnet of 192.168.1.0/24 and a WAN with Public IP, which should be reachable by the spoke.

'''Fortinet''' – '''Fortinet''' will act as a '''spoke'''. A spoke is a client, that will be connected to the hub (IPsec initiator). It will be connected to a '''hub''' for basic internet access. Fortinet has a LAN subnet of 192.168.5.0/24 and a WAN with private IP.

'''Fortinet''' – '''Fortinet''' will act as a '''spoke'''. A spoke is a client (IPsec initiator), that will be connected to the hub. It will be connected to a '''hub''' to be able to reach RUT LAN subnet. Fortinet has a LAN subnet of 192.168.5.0/24 and a WAN with private IP.
