NAT gateways are enterprise-class gateways that provide the Source Network Address Translation (SNAT) and Destination Network Address Translation (DNAT) features. Each NAT gateway provides a throughput capacity of up to 10 Gbit/s. NAT gateways also support cross-zone disaster recovery.

Examples

Basic info

Explore the status and billing method of your Alibaba Cloud Virtual Private Cloud (VPC) NAT gateways. This is useful for understanding the operational status and cost management of your NAT gateways across different regions.

select
  name,
  nat_gateway_id,
  vpc_id nat_type,
  status,
  description,
  billing_method,
  region,
  account_id
from
  alicloud_vpc_nat_gateway;

select
  name,
  nat_gateway_id,
  vpc_id nat_type,
  status,
  description,
  billing_method,
  region,
  account_id
from
  alicloud_vpc_nat_gateway;

List IP address details for NAT gateways

Determine the details of IP addresses associated with Network Address Translation (NAT) gateways to manage and monitor your network's internet connectivity and security.

select
  nat_gateway_id,
  address ->> 'IpAddress' as ip_address,
  address ->> 'AllocationId' as allocation_id
from
  alicloud_vpc_nat_gateway,
  jsonb_array_elements(ip_lists) as address;

select
  nat_gateway_id,
  json_extract(address.value, '$.IpAddress') as ip_address,
  json_extract(address.value, '$.AllocationId') as allocation_id
from
  alicloud_vpc_nat_gateway,
  json_each(ip_lists) as address;

List private network info for NAT gateways

Discover the segments that provide private network details for NAT gateways. This query can be used to assess the elements within your network infrastructure and optimize resource allocation based on bandwidth usage and zone distribution.

select
  name,
  nat_gateway_id,
  nat_gateway_private_info ->> 'EniInstanceId' as eni_instance_id,
  nat_gateway_private_info ->> 'IzNo' as nat_gateway_zone_id,
  nat_gateway_private_info ->> 'MaxBandwidth' as max_bandwidth,
  nat_gateway_private_info ->> 'PrivateIpAddress' as private_ip_address,
  nat_gateway_private_info ->> 'VswitchId' as vswitch_id
from
  alicloud_vpc_nat_gateway;

select
  name,
  nat_gateway_id,
  json_extract(nat_gateway_private_info, '$.EniInstanceId') as eni_instance_id,
  json_extract(nat_gateway_private_info, '$.IzNo') as nat_gateway_zone_id,
  json_extract(nat_gateway_private_info, '$.MaxBandwidth') as max_bandwidth,
  json_extract(nat_gateway_private_info, '$.PrivateIpAddress') as private_ip_address,
  json_extract(nat_gateway_private_info, '$.VswitchId') as vswitch_id
from
  alicloud_vpc_nat_gateway;

List NAT gateways that have traffic monitoring disabled

Identify instances where NAT gateways do not have traffic monitoring enabled. This can be useful in ensuring all gateways are properly configured for optimal security and performance.

select
  name,
  nat_gateway_id,
  ecs_metric_enabled
from
  alicloud_vpc_nat_gateway
where
  not ecs_metric_enabled;

select
  name,
  nat_gateway_id,
  ecs_metric_enabled
from
  alicloud_vpc_nat_gateway
where
  not ecs_metric_enabled;

List NAT gateways that have deletion protection disabled

Determine the areas in which NAT gateways lack deletion protection to enhance your network's security and prevent accidental data loss.

select
  name,
  nat_gateway_id,
  deletion_protection
from
  alicloud_vpc_nat_gateway
where
  not deletion_protection;

select
  name,
  nat_gateway_id,
  deletion_protection
from
  alicloud_vpc_nat_gateway
where
  deletion_protection = 0;

Count of NAT gateways per VPC ID

Assess the elements within your Alicloud Virtual Private Cloud (VPC) to understand the distribution of Network Address Translation (NAT) gateways. This allows for effective resource allocation and network planning.

select
  vpc_id,
  count(*) as nat_gateway_count
from
  alicloud_vpc_nat_gateway
group by
  vpc_id;

select
  vpc_id,
  count(*) as nat_gateway_count
from
  alicloud_vpc_nat_gateway
group by
  vpc_id;
