Before removing the NAT Gateway make sure you have removed the konfigurasi NAT Gateway: Floating IP, Static Route, NAT, and release the Interface used on the Instance. To ensure that no one is using the VPC, you can look in the Resource column, if it is marked "-", then there are no connected instances. The following is a guide to removing NAT Gateway on the Cloudeka portal service:
On the Network menu, select the Expert type VPC label that you want to delete and press the Delete button.
A confirmation window appears, click Confirm to continue the process.
A notification "NAT Gateway vpc-router has been successfully deleted" appears that the NAT Gateway has been successfully deleted.
