Specify the IPSec Network Settings.
[Use PFS]
Select the check box to enable Perfect Forward Secrecy (PFS) for IPSec session keys. Enabling PFS enhances the security while
increasing the load on the communication. Make sure that PFS is also enabled for the other devices.
[Specify by Time]/[Specify by Size]
Set the conditions for terminating a session for IPSec SA. IPSec SA is used as a communication tunnel. Select either or both of the
check boxes as necessary. If both check boxes are selected, the IPSec SA session is terminated when either of the conditions has
been satisfied.

[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.

Verifying Key Pairs and Digital Certificates
Enter a time in minutes to specify how long a session lasts.
Enter a size in megabytes to specify how much data can be transported in a session.
To enable the ESP authentication, select [SHA1] for the hash algorithm. Select [Do Not Use] if you want
to disable the ESP authentication.
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.
