natIpAllocateOption property
Specify the NatIpAllocateOption, which can take one of the following values: - MANUAL_ONLY: Uses only Nat IP addresses provided by customers. When there are not enough specified Nat IPs, the Nat service fails for new VMs. - AUTO_ONLY: Nat IPs are allocated by Google Cloud Platform; customers can't specify any Nat IPs. When choosing AUTO_ONLY, then nat_ip should be empty.
