"There are two types of data transmission modes in a network. The first is tunnel mode. Tunnel mode transports and protects data in network-to-network or site-to-site situations. It encapsulates the entire IP packet, including the data, the original IP header, and a new IP header. It also protects the user data. Transport mode is the second method for sending data across the network. This mode protects the data in host-to-host or end-to-end situations. In transport mode, IPsec protects the data in the original IP datagram by excluding the IP header, thereby only protecting the upper-layer protocols of IP payload."
