Site-to-Site VPN attachments in AWS Cloud WAN
Attaching a Site-to-Site VPN connection to your core network edge, first requires that you create a Site-to-Site VPN connection with Target Gateway Type set to Not Associated. See Create an AWS Cloud WAN Site-to-Site VPN attachment in the AWS Site-to-Site VPN User Guide.
Note
-
Your Site-to-Site VPN must be attached to a core network before you can start configuring a customer gateway. AWS doesn't provision these endpoints until the Site-to-Site VPN is attached to the core network.
-
A Site-to-Site VPN attachment must be created in the same AWS account that owns the core network.
