of packets, including packet headers.
Note that you cannot specify this protocol when [Tunnel] is selected for [Encapsulation
Type].
• [Authentication Algorithm for AH]
Specify the authentication algorithm to be applied when [AH] or [ESP&AH] is selected for
[Security Protocol] from the following:
[MD5], [SHA1]
• [Encryption Algorithm for ESP]
Specify the encryption algorithm to be applied when [ESP] or [ESP&AH] is selected for
[Security Protocol] from the following:
[None], [DES], [3DES], [AES-128], [AES-192], [AES-256]
