To connect applications to MongoDB Atlas clusters/project via Google Private Service Connect, the documentation says we need to reserve 50 IP addresses in our subnet: https://www.mongodb.com/docs/atlas/security-private-endpoint/ Each private endpoint in Google Cloud reserves an IP address within your Google Cloud VPC and forwards traffic from the endpoints' IP addresses to the service attachments . You must create an equal number of private endpoints to the number of service attachments. The number of service attachments defaults to 50. We would like the ability to not have to reserve 50 IP addresses per project as we have limited internal subnets. We would prefer to 1-3 IP addresses/service attachments per cluster/project.
