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 (Figure11-10)
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. (Figure11-11)
