Authentication applied to all of the packet except for the IP header is tunnel mode. In tunnel mode, the entire IP packet, including the IP header, is encapsulated within another IP packet. The outer IP header contains the source and destination addresses for the tunnel, while the inner IP header contains the source and destination addresses for the original packet. The authentication is applied to the outer IP header only, so that the inner IP header and the data it contains are not authenticated.
