User Name This field is applicable when you select PPTP or L2TP w/ or
w/out IPSec policy above.
Password This field is applicable when you select PPTP or L2TP w/ or
w/out IPSec policy above.
PPP Authentication This field is applicable when you select PPTP or L2TP w/ or
w/out IPSec policy above. PAP/CHAP is the most common
selection due to wild compatibility.
VJ compression This field is applicable when you select PPTP or L2TP w/ or
w/out IPSec policy above. VJ Compression is used for TCP/IP
protocol header compression. Normally set to Yes to improve
bandwidth utilization.
IKE Pre-Shared Key Click this button to input 1-63 characters as pre-shared key.
IPSec Security Method This group of fields is a must for IPSec Tunnels and L2TP with
IPSec Policy.
Medium Authentication Header (AH) means data will be authenticated,
but not be encrypted. By default, this option is active.
High (ESP-Encapsulating Security Payload)- means payload
(data) will be encrypted and authenticated. Select from below:
DES without Authentication -Use DES encryption algorithm
and not apply any authentication scheme.
DES with Authentication-Use DES encryption algorithm and
apply MD5 or SHA-1 authentication algorithm.
3DES without Authentication-Use triple DES encryption
algorithm and not apply any authentication scheme.
3DES with Authentication-Use triple DES encryption
algorithm and apply MD5 or SHA-1 authentication algorithm.
AES without Authentication-Use AES encryption algorithm
and not apply any authentication scheme.
AES with Authentication-Use AES encryption algorithm and
apply MD5 or SHA-1 authentication algorithm.
Advanced Specify mode, proposal and key life of each IKE phase,
Gateway etc.
The window of advance setup is shown as below:
IKE phase 1 mode -Select from Main mode and Aggressive
mode. The ultimate outcome is to exchange security proposals
to create a protected secure channel. Main mode is more secure
than Aggressive mode since more exchanges are done in a
secure channel to set up the IPSec session. However, the
Aggressive mode is faster. The default value in Vigor router is
