21.4.2 Encapsulation

The two modes of operation for IPSec VPNs are

Transport

mode and

Tunnel

mode. At the time of writing, the ZyXEL Device supports

Tunnel

mode only.

Figure 121

Transport and Tunnel Mode IPSec Encapsulation

Transport Mode

Transport

mode is used to protect upper layer protocols and only affects the data

in the IP packet. In

Transport

mode, the IP packet contains the security protocol

(

AH

or

ESP

) located after the original IP header and options, but before any upper

layer protocols contained in the packet (such as TCP and UDP).

With

ESP,

protection is applied only to the upper layer protocols contained in the

packet. The IP header information and options are not used in the authentication
process. Therefore, the originating IP address cannot be verified for integrity
against the data.

With the use of

AH

as the security protocol, protection is extended forward into

the IP header to verify the integrity of the entire packet by use of portions of the
original IP header in the hashing process.

Tunnel Mode

Tunnel

mode encapsulates the entire IP packet to transmit it securely. A

Tunnel

mode is required for gateway services to provide access to internal systems.

Tunnel

mode is fundamentally an IP tunnel with authentication and encryption.

This is the most common mode of operation.

Tunnel

mode is required for

gateway to gateway and host to gateway communications.

Tunnel

mode

communications have two sets of IP headers:

•

Outside header

: The outside IP header contains the destination IP address of

the VPN gateway.

•

Inside header

: The inside IP header contains the destination IP address of the

final system behind the VPN gateway. The security protocol appears after the

outer IP header and before the inside IP header.
