4.4.7 VPN Settings for Configuration Provisioning Advanced Wizard - Phase
2
Phase 2 in an IKE uses the SA that was established in phase 1 to negotiate SAs for IPSec.

VPN for Configuration Provisioning Advanced Wizard: Phase 2 Settings
•
Active Protocol
:
ESP
is compatible with NAT.
AH
is not available in this wizard.
•
Encapsulation
:
Tunnel
is compatible with NAT,
Transport
is not.
•
Encryption Algorithm
:
3DES
and
AES
use encryption. The longer the
AES
key, the higher the
security (this may affect throughput).
Null
uses no encryption.
•
Authentication Algorithm
: MD5 (Message Digest 5) and SHA (Secure Hash Algorithm) are
hash algorithms used to authenticate packet data.
MD5
gives minimal security.
SHA1
gives
higher security and
SHA256
gives the highest security. The stronger the algorithm, the slower it
is.
•
SA Life Time
: Set how often the USG renegotiates the IKE SA. A short SA life time increases
security, but renegotiation temporarily disconnects the VPN tunnel.
•
Perfect Forward Secrecy (PFS):
Disabling PFS allows faster IPSec setup, but is less secure.
Select DH1, DH2 or DH5 to enable PFS.
DH5
is more secure than
DH1
or
DH2
(although it may
affect throughput). 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. DH5 refers to Diffie-Hellman Group 5 a
1536 bit random number (more secure, yet slower).
•
Local Policy (IP/Mask)
: Type the IP address of a computer on your network. You can also
specify a subnet. This must match the remote IP address configured on the remote IPSec device.
•
Remote Policy (IP/Mask)
:
Any
displays in this field because it is not configurable in this
wizard.
•
Nailed-Up
: This displays for the site-to-site and remote access client role scenarios. Select this
to have the USG automatically renegotiate the IPSec SA when the SA life time expires.
