Internet Key Exchange Settings
IKE is a keying protocol that allows automatic negotiation and authentication,
IKE Phase 1 authenticates the IPSec peers and sets up a secure channel between the peers to enable IKE exchanges. IKE Phase 2 negotiates IPSec SAs to set up the IPSec tunnel.
1.Under IKE Phase 1, in the Key Lifetime field, type length of time this key will live in Seconds, Minutes, or Hours. When a key reaches its lifetime, the SA is renegotiated and the key is regenerated or refreshed.
