==Introduction==

Normally we configure IPsec for LAN-to-LAN communication which is also known as split-tunnel VPN when only specific hosts should be reachable via VPN tunnel. However, we may also take a different approach and configure VPN tunnel using 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 typical default route.
