WebIn the IPv6 environment, the AH or ESP header appears after the Hop-by-Hop, Destination, Routing and Fragment extensions. For tunnel mode, the AH or ESP header encapsulates the source IP packet, and the whole is encapsulated in its turn by a new IP header. The tunnel corresponds to a data structure in which an IP packet contains another IP packet. WebDec 6, 2024 · Also known as a transport layer security protocol, the Encapsulating Security Payload is able to function with both the IPv6 and IPv4 protocols. The way ESP operates is pretty straightforward: It is inserted between the Internet Protocol/IP header and upper layer protocols such as UDP, ICMP or TCP. In this position, the ESP takes the form of a ...
