DESCRIPTION
(ALPHA) gcloud alpha compute routers nats create is used to create a NAT on a Compute Engine router.
EXAMPLES
Auto-allocate NAT for all IP addresses of all subnets in the region:
gcloud alpha compute routers nats create 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.

gcloud alpha compute routers nats create nat1 --router=my-router --nat-external-ip-pool=ip-address1,ip-address2

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.

gcloud alpha compute routers nats create nat1 --router=my-router --auto-allocate-nat-external-ips --nat-custom-subnet-ip-ranges=subnet-1,subnet-3:secondary-range-1
POSITIONAL ARGUMENTS
NAME
Name of the NAT to create
REQUIRED FLAGS
--router=ROUTER
The Router to use for NAT.
Exactly one of these must be specified:
--nat-all-subnet-ip-ranges
Allow all IP ranges of all subnetworks in the region, including primary and secondary ranges, to use NAT.
--nat-custom-subnet-ip-ranges=SUBNETWORK[:RANGE_NAME|:ALL],[…]
List of subnetwork primary and secondary IP ranges to be allowed to use NAT.
  • SUBNETWORK:ALL - specifying a subnetwork name with ALL includes the primary range and all secondary ranges of the subnet.
  • SUBNETWORK - including a subnetwork name includes only the primary subnet range of the subnetwork.
  • SUBNETWORK:RANGE_NAME - specifying a subnetwork and secondary range name includes only that secondary range. It does not include the primary range of the subnet.
--nat-primary-subnet-ip-ranges
Allow only primary IP ranges of all subnetworks in the region to use NAT.
OPTIONAL FLAGS
--async
Return immediately, without waiting for the operation in progress to complete.
--auto-network-tier=AUTO_NETWORK_TIER
The network tier to use when automatically reserving NAT IP addresses. AUTO_NETWORK_TIER must be one of:
PREMIUM
High quality, Google-grade network tier with support for all networking products.
STANDARD
Public internet quality, with only limited support for other networking products.
--[no-]enable-dynamic-port-allocation
Enable dynamic port allocation.

If not specified, Dynamic Port Allocation is disabled by default.

Use --enable-dynamic-port-allocation to enable and --no-enable-dynamic-port-allocation to disable.

--enable-endpoint-independent-mapping
Enable endpoint-independent mapping for the NAT (as defined in RFC 5128).

If not specified, NATs have endpoint-independent mapping disabled by default.

Use --no-enable-endpoint-independent-mapping to disable endpoint-independent mapping.

--enable-logging
Enable logging for the NAT. Logs will be exported to Stackdriver. NAT logging is disabled by default. To disable logging for the NAT, use $ gcloud alpha compute routers nats update MY-NAT \ --no-enable-logging --router ROUTER --region REGION
--endpoint-types=[ENDPOINT_TYPE,…]
Endpoint Types supported by the NAT Gateway.
ENDPOINT_TYPE must be one of:
ENDPOINT_TYPE_VM
  For VM Endpoints
ENDPOINT_TYPE_SWG
  For Secure Web Gateway Endpoints
ENDPOINT_TYPE_MANAGED_PROXY_LB
  For regional Application Load Balancers (internal and external) and regional proxy Network Load Balancers (internal and external) endpoints

The default is ENDPOINT_TYPE_VM.

ENDPOINT_TYPE must be one of: ENDPOINT_TYPE_VM, ENDPOINT_TYPE_SWG, ENDPOINT_TYPE_MANAGED_PROXY_LB.

--icmp-idle-timeout=ICMP_IDLE_TIMEOUT
Timeout for ICMP connections. See https://cloud.google.com/sdk/gcloud/reference/topic/datetimes for information on duration formats.
--log-filter=LOG_FILTER
Filter for logs exported to stackdriver.

The default is ALL.

If logging is not enabled, filter settings will be persisted but will have no effect.

Use --[no-]enable-logging to enable and disable logging.

LOG_FILTER must be one of:

ALL
Export logs for all connections handled by this NAT.
ERRORS_ONLY
Export logs for connection failures only.
TRANSLATIONS_ONLY
Export logs for successful connections only.
--max-ports-per-vm=MAX_PORTS_PER_VM
Maximum ports to be allocated to a VM.

This field can only be set when Dynamic Port Allocation is enabled and defaults to 65536. It must be set to a power of 2 that is greater than minPortsPerVm and at most 65536.

--min-ports-per-vm=MIN_PORTS_PER_VM
Minimum ports to be allocated to a VM.

If Dynamic Port Allocation is disabled, this defaults to 64.

If Dynamic Port Allocation is enabled, this defaults to 32 and must be set to a power of 2 that is at least 32 and lower than maxPortsPerVm.

--region=REGION
Region of the NAT to create. If not specified, you might be prompted to select a region (interactive mode only).

To avoid prompting when this flag is omitted, you can set the compute/region property:

gcloud config set compute/region REGION

A list of regions can be fetched by running:

gcloud compute regions list

To unset the property, run:

gcloud config unset compute/region

Alternatively, the region can be stored in the environment variable CLOUDSDK_COMPUTE_REGION.

--rules=RULES
Path to YAML file containing NAT Rules applied to the NAT. The YAML file format must follow the REST API schema for NAT Rules. See API Discovery docs for reference.
--tcp-established-idle-timeout=TCP_ESTABLISHED_IDLE_TIMEOUT
Timeout for TCP established connections. See https://cloud.google.com/sdk/gcloud/reference/topic/datetimes for information on duration formats.
--tcp-time-wait-timeout=TCP_TIME_WAIT_TIMEOUT
Timeout for TCP connections in the TIME_WAIT state. See https://cloud.google.com/sdk/gcloud/reference/topic/datetimes for information on duration formats.
--tcp-transitory-idle-timeout=TCP_TRANSITORY_IDLE_TIMEOUT
Timeout for TCP transitory connections. See https://cloud.google.com/sdk/gcloud/reference/topic/datetimes for information on duration formats.
--type=TYPE
Type of the NAT Gateway. Defaults to PUBLIC if not specified. TYPE must be one of:
PRIVATE
Used for private-to-private NAT translations. Allows communication between VPC Networks.
PUBLIC
Used for private-to-public NAT translations. Allows VM instances to communicate with the internet.
--udp-idle-timeout=UDP_IDLE_TIMEOUT
Timeout for UDP connections. See https://cloud.google.com/sdk/gcloud/reference/topic/datetimes for information on duration formats.
At most one of these can be specified:
--auto-allocate-nat-external-ips
Automatically allocate external IP addresses for Cloud NAT
--nat-external-ip-pool=IP_ADDRESS,[IP_ADDRESS,…]
External IP Addresses to use for Cloud NAT

API REFERENCE
This command, when specified without alpha or beta, uses the compute/v1/routers API. The full documentation for this API can be found at: https://cloud.google.com/compute/docs/reference/rest/v1/routers/

The beta command uses the compute/beta/routers API. The full documentation for this API can be found at: https://cloud.google.com/compute/docs/reference/rest/beta/routers/

The alpha command uses the compute/alpha/routers API. Full documentation is not available for the alpha API.

NOTES
This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. These variants are also available:
