SA Lifetime: Specify the number of minutes that a Security Association (SA) will stay
active before new encryption and authentication key will be exchanged. There are two
kinds of SAs, IKE and IPSec. IKE 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 240 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.
Select the Apply button to update the settings.
