AWS Site-to-Site VPN now supports Internet Key Exchange (IKE) initiation
You can now initiate Internet Key Exchange (IKE) negotiations for your VPN connections from AWS. This feature is available for new and existing Site-to-Site VPN connections and can be accessed through the AWS Management console, AWS Cloud Development Kit (CDK), or the AWS Command Line Interface (CLI). AWS Site-to-Site VPN connections offer IPSec tunnels which use the IKE protocol to establish a tunnel. With this feature, AWS VPN endpoints will send the initial IKE message to your Customer Gateway (CGW). AWS endpoints will initiate when new VPNs are created or if the tunnel goes down. For more information, please see the documentation.
