Step5.
In Encapsulation, select ISAKMP Algorithm, as both sides start to build the connection, and
select the algorithm to use. In ENC Algorithm (3DES/DES/AES), select 3DES. In AUTH
Algorithm (MD5/SHA1), select MD5. In Group (GROUP 1, 2, 5), select GROUP 1, the both
sides need to select the same group.
Step6.
In IPSec Algorithm, select Data Encryption + Authentication, or select Authentication Only.
In ENC Algorithm (3DES/DES/AES/NULL), select 3DES. In AUTH Algorithm (MD5/SHA1),
select MD5, to assure the Data Encryption + Authentication Method.
