Auto-allocate NAT for all IP addresses of all subnets in the region:

$ {command} nat1 --router=my-router

--auto-allocate-nat-external-ips --nat-all-subnet-ip-ranges

Specify IP addresses for NAT:

Each IP address is the name of a reserved static IP address resource in

the same region.

Specify subnet ranges for NAT:

By default, NAT works for all primary and secondary IP ranges for all

subnets in the region for the given VPC network. You can restrict which

subnet primary and secondary ranges can use NAT.
