[Select Algorithm]
Select the [ESP], [ESP (AES-GCM)], or [AH (SHA1)] check box(es) depending on the IPSec header and the

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.

specify the algorithm, or select [Do Not Use] if you want to disable the ESP encryption.
