IAP TCP forwarding allows you to establish an encrypted tunnel over which you can forward SSH, RDP, and other traffic to VM instances. IAP TCP forwarding also provides you fine-grained control over which users are allowed to establish tunnels and which VM instances users are allowed to connect to.<\/p>\n

1. Ensure that the IP range 35.235.240.0\/20 is added as a source in your firewall rules for TCP port 22.<\/h3>\n

To allow RDP and SSH access to all VM instances in your network, do the following:<\/p>\n

    \n
  1. Open the Firewall Rules page.<\/li>\n
  2. Select a Google Cloud project.<\/li>\n
  3. On the Firewall Rules page, click Create firewall rule<\/strong>.<\/li>\n
  4. Configure the following settings:<\/li>\n

    Name:<\/strong> allow-ingress-from-iap
    \nDirection of traffic: Ingress<\/strong>
    \nTarget: All instances in the network
    \nSource filter: IP ranges<\/strong>
    \nSource IP ranges:<\/strong> 35.235.240.0\/20
    \nProtocols and ports:<\/strong> Select TCP and enter 22,3389 to allow both RDP and SSH.<\/p>\n

  5. Click Create.<\/li>\n<\/ol>\n

    2. Verify that the necessary IAM roles are assigned to the user who needs SSH access to the machine.<\/h3>\n\n\n\n\n\n\n

    3. Confirm that your VM is configured to allow SSH on port 22:<\/h3>\n

    Go to your VM instance and click it
    \nEdit mode
    \nFind for Management section
    \nLook for Automation section
    \nInside the text box, type \"ufw allow 22\"
    \nSave
    \nStop VM instance
    \nStart VM instance
