This object specifies the state of this tunnel. 1. closed - The tunnel does not exist between the peers because it was not negotiated yet, or because last tunnel closed normally due to hard timeout, clear by admin or DELETE received from the remote peer. This is also the initial state of the row when it is created. 2. inProgress - The tunnel does not exist between peers, but it is currently being negotiated in IKE Quick Mode. 3. established - The tunnel exists between peers. 4. failed - The tunnel does not exist between peers because of a failure: 1. Last time we tried to establish this tunnel the negotiation failed. 2. The connection with the remote peer has failed due to one of the following, and hence all the corresponding ipsec tunnels were closed: a. Last time we tried to establish IKE the negotiation failed. b. During last connection a track object signaled a connection failure. c. The interface used for local-address does not have an IP address asigned to it 1 minute or more after this row was created. NOTE: The word 'tunnel' in this context refers to 1 or more IPSec SAs (ESP or AH) between the peers, pertaining to the proxy addresses specified in this entry. As long as there is at least 1 SA established, the tunnel state shall remain 'established'.
