This field is applicable when you select ISDN, PPTP or L2TP
with or without IPSec policy above. VJ Compression is used
for TCP/IP protocol header compression. Normally set to Yes
to improve bandwidth utilization.
This group of fields is applicable for IPSec Tunnels and L2TP
with IPSec Policy.
Pre-Shared Key-Input 1-63 characters as pre-shared key.
Digital Signature (X.509) - Select one predefined in the
X.509 Peer ID Profiles.
This group of fields is a must for IPSec Tunnels and L2TP
with IPSec Policy.
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.
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
Main mode.
