# Auto Scaling integration

Available in Classic

You can configure newly scaled servers to automatically use a NAT Gateway by integrating with Auto Scaling.

## How to integrate with Auto Scaling

To configure a NAT Gateway to be automatically applied when servers are created through Auto Scaling:

              Note

              

You configure the integration between the NAT Gateway and Auto Scaling during the Auto Scaling Group creation process. For more information about creating an Auto Scaling Group, see [Create Auto Scaling Group (Classic)](/docs/en/compute-autoscaling-autoscalingconsole#AutoScalingGroup%EC%83%9D%EC%84%B1%ED%95%98%EA%B8%B0Classic).

1. Check the NAT Gateway and Peer Host to be associated with the servers newly created by Auto Scaling. If necessary, create a new NAT Gateway and Peer Host.
  - For more information, see the [NAT Gateway](/docs/en/natgw-natgw-classic) and [Peer Host](/docs/en/natgw-peerhost-classic) user guides.
2. In the Classic environment of the NAVER Cloud Platform console, navigate to **Menu** > **All Services > Compute > Auto Scaling > Auto Scaling Group**.
3. Click **[Create Auto Scaling Group]**.
4. Proceed with the Auto Scaling Group creation steps. In step 2, the group configuration interface, set the **NAT Gateway** option to **Subscribe**, then configure the NAT Gateway and Peer Host you checked in step 1. ![natgw-autoscaling-classic_setting_ko](https://cdn.document360.io/6998976f-9d95-4df8-b847-d375892b92c2/Images/Documentation/natgw-autoscaling-classic_setting_en.png?sv=2026-02-06&spr=https&st=2026-11-14T04%3A50%3A45Z&se=2026-11-14T05%3A50%3A45Z&sr=c&sp=r&sig=fDuWPLryo%2FDiCRsV%2B30yzWlIA9hSQqd9NcfgbUkAO0g%3D)

              Caution

              

When applying Auto Scaling, you can specify only 1 NAT Gateway.
5. Complete the Auto Scaling Group creation steps in order.
