Environment: Google Cloud w/ GSuite Requirement: Users on Windows/Linux/Android/iOS need to be able to VPN into VPC of a Google Project. Ideally integrate with the user accounts in GSuite (Cloud Identity)
GCloud: "Cloud VPN only supports site-to-site IPsec VPN connectivity, subject to the requirements listed in this section. It does not support client-to-gateway (road warrior) scenarios. In other words, Cloud VPN doesn't support use cases where client computers need to "dial in" to a VPN using client VPN software."

Therefore Cloud VPN does NOT appear to be a valid option.
Other Hyperscalers appear to address this need, but not Google.
