groups: Group 1/ Group 2/ Group 5. 
  Phase1/Phase2 Encryption: This option allows users to set this VPN channel to 
use any encryption mode. Note that this parameter must be identical to that of the 
remote  encryption  parameter:  DES  (64  -  bit  encryption  mode),  3DES  (128-bit 
encryption mode), AES (the standard of using security code to encrypt information). 
It supports 128-bit, 192-bit, and 256-bit encryption keys. 
  Phase 1/Phase 2 Authentication: This authentication option allows users to set 
this VPN tunnel to use any authentication mode. Note that this parameter must be 
identical to that of the remote authentication mode: ―MD5‖ or ―SHA1‖.   
  Phase1 SA Life Time: The life time for this exchange code is 28800 seconds (or 8 
hours) by default. This allows the automatic generation of other exchange passwords 
within the valid time of the VPN connection so as to guarantee security. 
  Phase2 SA Life Time: The life time for this exchange code is 3600 seconds (or 1 
hour) by default. This allows the automatic generation of other exchange passwords 
within the valid time of the VPN connection so as to guarantee security. 
  Preshared Key: For the Auto (IKE) option, enter a password of any digit or character 
in the text of ―Pre-shared Key‖ (the example here is set as test), and the system will 
automatically translate what users entered as exchange password and authentication 
mechanism during the VPN tunnel connection. This exchange password can be made 
up of up to 30 characters.
