Step 14.
Under the ISAKMP Algorithm section, select "3DES" for
Encryption Algorithm; select "MD5" for Authentication Algorithm;
select "DH 1" for Key Group.
Step 15.
Select Use both algorithms below the IPSec Algorithm, or tick Use
authentication algorithm only. If ticked Use both algorithms, please
select "3DES" for Encryption Algorithm and "MD5" for Authentication
Algorithm.
Step 16.
Select "Group 1" for PFS Key Group. Enter "3600" in the ISAKMP
SA Lifetime field and "28800" in the IPSec SA Lifetime field and then
select "Main Mode" for Mode.
Step 17.
For GRE Tunnel Settings, type "192.168.60.100" in the Local
Endpoint Address field and "192.168.60.200" in the Remote Endpoint
Address field. (Note: The local IP and the remote IP must be configured in
the same class C network.)
