Transport mode
The IPsec protocols can be implemented in host-to-host transport mode, as well as in a network tunneling mode. In the transport mode, IPsec only encrypts the payload of the IP packet. No other part of the IP packet is tampered with. Since the IP header is neither modified nor encrypted, the network routing for each packet remains intact.
