17 IPSec Concepts Transport mode and tunnel mode Transport mode adds an authentication header (AH) before the IP header. Only a single pair of addresses is used (those in the IP header). When transport mode is used, both endpoints implement IPSec. Tunnel mode encapsulates an IP datagram in a new datagram, with a new IP header specifying the addresses of the tunnel end points. IPSec is implemented between tunnel endpoints. IPSec is transparent to the actual endpoints within the IP header in the original packet. Figure 133 provides a basic visual comparison of how transport mode and tunnel mode modify an IP datagram.

IPSec Concepts

Transport mode and tunnel mode

Transport mode adds an authentication header (AH) before the IP header. Only a single pair of

addresses is used (those in the IP header). When transport mode is used, both endpoints

implement IPSec.

Tunnel mode encapsulates an IP datagram in a new datagram, with a new IP header specifying the

addresses of the tunnel end points. IPSec is implemented between tunnel endpoints. IPSec is

transparent to the actual endpoints within the IP header in the original packet.

Figure 133

provides a basic visual comparison of how transport mode and tunnel mode modify an

IP datagram.
