Phase 2 in an IKE uses the SA that was established in phase 1 to negotiate SAs for IPSec.
SA Life Time
(Seconds)
Define the length of time before an IKE SA automatically renegotiates in this field.
The minimum value is 60 seconds.
A short SA Life Time increases security by forcing the two VPN gateways to update
the encryption and authentication keys. However, every time the VPN tunnel
renegotiates, all users accessing remote resources are temporarily disconnected.
NAT Traversal
Select this check box to enable NAT traversal. NAT traversal allows you to set up a
VPN connection when there are NAT routers between the two IPSec routers.
Note: The remote IPSec router must also have NAT traversal
enabled. See
for more on NAT traversal.
Dead Peer
Detection
(DPD)
Select this check box if you want the ZyWALL to make sure the remote IPSec router
is there before it transmits data through the IKE SA. If there has been no traffic for at
least 15 seconds, the ZyWALL sends a message to the remote IPSec server. If the
remote IPSec server responds, the ZyWALL transmits the data. If the remote IPSec
server does not respond, the ZyWALL shuts down the IKE SA.
Authentication
Method
Pre-Shared
Key
Type your pre-shared key in this field. A pre-shared key identifies a communicating
party during a phase 1 IKE negotiation. It is called "pre-shared" because you have to
share it with another party before you can communicate with them over a secure
connection.
Type from 8 to 31 case-sensitive ASCII characters or from 16 to 62 hexadecimal ("0-
9", "A-F") characters. Precede hexadecimal characters with “0x”.
Both ends of the VPN tunnel must use the same pre-shared key. You will receive a
PYLD_MALFORMED (payload malformed) packet if the same pre-shared key is not
used on both ends.
Certificate
Use the drop-down list box to select the certificate to use for this VPN tunnel. You
must have certificates already configured in the
My Certificates
screen. Click
Certificate
under the
Object
menu to go to the
My Certificates
screen where you
can view the ZyWALL's list of certificates.
