Setting
Specify the security protocol
to be used in Phase 2.
To apply both encryption and
authentication to sent data,
specify "ESP" or "ESP+AH".
To apply authentication data
only, specify "AH".
(auto setting)
Specify the authentication
algorithm to be used in phase
2.
(auto setting)
Specify the encryption
algorithm to be used in phase
2.
(auto setting)
Specify whether to activate
PFS. Then, if PFS is activated,
select the Diffie-Hellman
group.
(auto setting)
Specify the time period for
which the SA settings in phase
2 are valid.
