STEP 5﹒Select ISAKMP Algorithm in Encapsulation list. Choose the Algorithm when
setup connection. Please select ENC Algorithm (3DES/DES/AES), AUTH
Algorithm (MD5/SHA1), and Group (GROUP1, 2,5). Both sides have to choose
the same group. Here we select 3DES for ENC Algorithm, MD5 for AUTH
Algorithm, and GROUP1 for group.
STEP 6﹒You can choose Data Encryption+Authentication or Authentication Only to
communicate in IPSec Algorithm list:
ENC Algorithm: 3DES/DES/AES/NULL
AUTH Algorithm: MD5/SHA1
Here we select 3DES for ENC Algorithm and MD5 for AUTH Algorithm to
make sure the encapsulation way for data transmission
