Is there any difference/advantage in using an "ip in ip tunnel encrypted with ipsec transport mode" over using directly the "ipsec tunnel mode".

An IP in IP tunnel has a tunnel device at each end, and the tunnel creates a virtual point-to-point connection between them. The tunnel may then be encrypted using IPsec transport mode. Traffic is sent through the tunnel by routing it to the IP address of the tunnel interface at the other end. In IPsec tunnel mode, it appears to the routers as if traffic is simply routed to the existing gateway. There is no tunnel interface, and the tunnel definitions at each end decide which traffic is to go through the tunnel.
