 Note that in the example we allocate 3 IPs because we will be provisioning 3 NAT Gateways (due to `single_nat_gateway = false` and having 3 subnets).
 If, on the other hand, `single_nat_gateway = true`, then `aws_eip.nat` would only need to allocate 1 IP.
-Passing the IPs into the module is done by setting variable `external_nat_ip_ids = ["${resource.aws_eip.nat.*.id}"]`.
