thanks maripages, you are correct. It should say specify an IP range that is routable on your network via a Transit VPC or AWS Transit GW, whatever your solution may be. More detail can be found here: docs.aws.amazon.com/fsx/latest/ONTAPGuide/access-environments.html
5:12 - Correction required. It won't accept an IP range from VPC. The Endpoint IP range should not overlap with VPC.

updates allow an Endpoint IP range from your VPC to be used now. Choose "Unallocated IP address range from your VPC" option. Much simpler!
