Remediation

From Google Cloud Console​

  1. Go to the VM instances page by visiting: https://console.cloud.google.com/compute/instances.
  2. Click on the instance name to go the the Instance detail page.
  3. Click Edit.
  4. For each Network interface, ensure that External IP is set to None.
  5. Click Done and then click Save.

From Google Cloud CLI​

  1. Describe the instance properties:

    gcloud compute instances describe {{instance-name}} \
        --zone={{zone}}

  2. Identify the access config name that contains the external IP address. This access config appears in the following format:

    networkInterfaces: 
    - accessConfigs: 
        - kind: compute#accessConfig 
            name: External NAT 
            natIP: 130.211.181.55 
            type: {{one-to-one-nat}}

  3. Delete the access config.

    gcloud compute instances delete-access-config {{instance-name}} \
        --zone={{zone}} \
        --access-config-name {{access-config-name}}

In the above example, the ACCESS_CONFIG_NAME is External NAT. The name of your access config might be different.
