WebHowever, in ESP the Next Header field appears after the encrypted data, and so “points back” to one of the following: a Destination Options extension header (if present), a TCP/UDP header (in transport mode) or an IPv4/IPv6 header (in tunnel mode). This too is shown in Figure 124 and Figure 125. 3. ESP Authentication Field Calculation and Placement 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. csr in small businesses
