[Select Algorithm]
Select the [ESP], [ESP (AES-GCM)], or [AH (SHA1)] check box(es) depending on the IPSec header and the
algorithm used. AES-GCM is an algorithm for both authentication and encryption. If [ESP] is selected, also
select algorithms for authentication and encryption from the [ESP Authentication] and [ESP Encryption] drop-
down lists.
[ESP Authentication] To enable the ESP authentication, select [SHA1] for the hash algorithm. Select [Do Not
Use] if you want to disable the ESP authentication.
[ESP Encryption] Select the encryption algorithm for ESP. You can select [NULL] if you do not want to
specify the algorithm, or select [Do Not Use] if you want to disable the ESP encryption.
[Connection Mode]
The connection mode of IPSec is displayed. The machine supports transport mode, in which the payloads of
IP packets are encrypted. Tunnel mode, in which whole IP packets (headers and payloads) are encapsulated
