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. (Figure 17-49)

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. (Figure 17-50)

STEP 7. After selecting GROUP1 in Perfect Forward Secrecy, enter 3600 seconds in
ISAKMP Lifetime, enter 28800 seconds in IPSec Lifetime, and selecting Main
mode in Mode. (Figure 17-51)
