Detaching a NAT gateway from a route table
Deleting a NAT gateway

If you no longer need a NAT gateway, you can delete it. Before deleting a NAT gateway, detach it from all route tables that use it.

Detaching a NAT gateway from a route table

Management console

CLI

Terraform

API

In the management console, go to the folder where you need to detach a NAT gateway.
In the list of services, select Virtual Private Cloud.
In the left-hand panel, select Routing tables.
In the list that opens, find the route table with the NAT gateway listed in its Static routes column.
In the line with the table, click and select Edit.
In the window that opens, click in the line with the NAT gateway name.
Click Save.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

To detach a NAT gateway from a route table:

View the description of the CLI command for editing a route table:
```
yc vpc route-table update --help
```

Get the name or ID of the route table the NAT gateway is attached to:

yc vpc route-table list

Result:

+----------------------+----------------------+-------------+----------------------+
|          ID          |         NAME         | DESCRIPTION |      NETWORK-ID      |
+----------------------+----------------------+-------------+----------------------+
| enpcaaqahk3c******** | test-table           |             | enptgj64mv2r******** |
+----------------------+----------------------+-------------+----------------------+

Detach the NAT gateway:

yc vpc route-table update <route_table_name_or_ID> --clear-routes

Use either the --id or --name parameter.

If you don't have Terraform, install it and configure the Yandex Cloud provider.

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the documentation on the Terraform website or mirror website.

To detach a NAT gateway from a route table created using Terraform:

Open the Terraform configuration file and find the fragment with the description of the route table the NAT gateway is attached to:

Example of a table description in the Terraform configuration

...
resource "yandex_vpc_route_table" "routetable" {
  folder_id  = "<user_folder_ID>"
  name       = "<route_table_name>"
  network_id = "<network_ID>"
  static_route {
    destination_prefix = "0.0.0.0/0"
    gateway_id         = <gateway_ID>
  }
}
...

Delete the static_route object.
In the command line, go to the directory with the Terraform configuration file.
Check the configuration using this command:
```
terraform validate
```
If the configuration is correct, you will get this message:
```
Success! The configuration is valid.
```
Run this command:
```
terraform plan
```
The terminal will display a list of resources with parameters. No changes will be made at this step. If the configuration contains any errors, Terraform will point them out.
Apply the configuration changes:
```
terraform apply
```
Confirm the changes: type yes into the terminal and press Enter.

You can check the update using the management console or this CLI command:
```
yc vpc route-table get <route_table_name_or_ID>
```
Use either the --id or --name parameter.

To detach a NAT gateway from a route table, delete the static route with that NAT gateway from the route table. To do this, use the update REST API method for the RouteTable resource or the RouteTableService/Update gRPC API call. In your request, provide a list of static routes without the route you want to delete under:

staticRoutes: For REST API
static_routes: For gRPC API

If the list contained a single static route, provide an empty list.

To get a list of static routes, use the get REST API method for the RouteTable resource or the RouteTableService/Get gRPC API call. In your request, provide the route table ID in this parameter:

routeTableId: For REST API
route_table_id: For gRPC API

Warning

The API method will assign default values to all the parameters of the object you are modifying unless you explicitly provide them in your request. To avoid this, list the settings you want to change in the updateMask parameter as a single comma-separated string.
