Hi,
The message "Tunnel is ready. Waiting for trigger event or peer to trigger negotiation" is an information that the device is ready to negotiate ike but there has been no event triggering it. Either this SRX is not configured to initiate the VPN or it is not receiving IKE packets from the other end.
From what I see from the logs the VPN seems to be working fine.
Hence, I suppose the VPN is set with APIPA IP address?
Is this seen on both ends of the tunnel or the end which has the static ip?
