negotiates and establishes SA on behalf of IPSec, an IKE SA is used by IKE.
Phase 1 (IKE): To issue an initial connection request for a new VPN tunnel. The range can be
from 5 to 15,000 minutes, and the default is 480 minutes.
Phase 2 (IPSec): To negotiate and establish secure authentication. The range can be from 5 to
15,000 minutes, and the default is 60 minutes.
A short SA time increases security by forcing the two parties to update the keys. However, every
time the VPN tunnel re-negotiates, access through the tunnel will be temporarily disconnected.
PING for Keep Alive:
None: The default setting is None. To this mode, it will not detect the remote IPSec peer has
been lost or not. It only follows the policy of Disconnection time after no traffic, which the remote
IPSec will be disconnected after the time you set in this function.
PING: This mode will detect the remote IPSec peer has lost or not by pinging specify IP address.
DPD:
Dead peer detection (DPD) is a keeping alive mechanism that enables the router to
be detected lively when the connection between the router and a remote IPSec peer has lost.
Please be noted, it must be enabled on the both sites.
PING to the IP: It is able to IP Ping the remote PC with the specified IP address and alert when the
connection fails. Once alter message is received, Router will drop this tunnel connection. Re-establish
of this connection is required. Default setting is 0.0.0.0 which disables the function.
Interval: This sets the time interval between Pings to the IP function to monitor the connection status.
Default interval setting is 10 seconds. Time interval can be set from 0 to 3600 second, 0 second
disables the function.
