8.6.23 VPN—IPsec
Description
There are 2 VPN communication modes: transport mode and tunnel mode.
Transport Mode
This mode is used when IPsec is applied between hosts or between a host and site. It is useful for remote
access. In this mode, the host itself encrypts the packet before sending it.
Tunnel Mode
This mode is used when IPsec is applied between sites.
In this mode, an SA (Security Association) is created between devices (called secure gateways) that
support IPsec. Data from other clients connected to these devices is encrypted and sent. A host’s data is
encrypted by a security gateway and sent to the corresponding security gateway.
The receiving security gateway decrypts the data and sends it to the destination host.
