Specify the PPP authentication method for PPTP, and L2TP
Authentication
over IPSec. Normally set to PAP/CHAP for the widest
compatibility.
VJ Compression
VJ Compression is used for TCP/IP protocol header
compression. Normally set to Yes to improve bandwidth
utilization.

Key
Please fill a Pre-shared Key and confirm it for this specific
node.
IPSec Security
Specify the IPSec security method, either authentication or
Method
encryption algorithm, to determine the security level. You can
only select one.
Medium(AH): Specify the IPSec protocol for the
Authentication Header protocol. The data will be
authenticated, but not be encrypted.
High (ESP): Specify the IPSec protocol for the Encapsulating
Security Payload protocol. The data will be encrypted.
Supported algorithms are listed 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.
