Perfect Forward 

Secret (PFS)

Perfect Forward Secret (PFS) is disabled (None) by default in phase 2 IPSec 

SA setup. This allows faster IPSec setup, but is not so secure. 
Select DH1 or DH2 to enable PFS. DH1 refers to Diffie-Hellman Group 1 a 768 

bit random number. DH2 refers to Diffie-Hellman Group 2 a 1024 bit (1Kb) 

random number (more secure, yet slower).
