Hi,

This is possible to use Certificate-based Authentication to deal with the dynamic IP issue. You can configure a CGW (Customer Gateway) without a static IP address.

Resolution:

1/ Create and install a root CA and a subordinate CA

2/ Create a private certificate to use as the identity certificate for your customer gateway

3/ Create a customer gateway for your VPN connection

4/ Configure the AWS Site-to-Site VPN connection with a virtual private gateway

5/ Copy the end entity certificate (the private certificate that you created in above task 2), root CA certificate, and subordinate CA certificate to the customer gateway device

  • Would this work in situations where the customer gateway is behind CGNat and doesn't have a publicly routable IP address at all?

  • Yes, as long as the VPN session is configured for NAT Traversal (NAT-T).

You can use certificates to authenticate the Customer Gateway, therefore removing the requirement for a static IP: https://aws.amazon.com/premiumsupport/knowledge-center/vpn-certificate-based-site-to-site/
