AWS SDN - dynamic addresses for S3 bucket

[j_bresee]

Hi!

I am trying to set up a vpn to AWS.  i would like to direct all traffic to an S3 bucket to transit the VPN.

I thought I could use the AWS SDN to grab the dynamic S3 IP's and then create a dynamic address.  I was thinking I would set up a static route to the VPN using the dynamic address.

Is this an appropriate use case for the AWS SDN?

Am I missing anything with this approach?

Thanks!
