title: Is it possible to use Google App Engine with Google Cloud VPN?
body: <p>The documentation from Google is not really clear about it.
  Here ( <a href="https://cloud.google.com/compute/docs/vpn/overview" rel="noreferrer">https://cloud.google.com/compute/docs/vpn/overview</a> ) it says </p>
  
  <blockquote>
    <p>Google Cloud VPN securely connects your existing network to your Google Cloud Platform (GCP) network through an IPsec VPN connection</p>
  </blockquote>
  
  <p>Considering that Both Google App Engine (GAE) and Google Compute Engine (GCE) are part of Google Cloud Platform (GCP), it would mean that Google Cloud VPN works for both GAE and GCE.</p>
  
  <p>Also, the section for Cloud VNP is at the same level than GAE and GCE in the project console : <a href="https://i.stack.imgur.com/OQIja.png" rel="noreferrer"><img src="https://i.stack.imgur.com/OQIja.png" alt="enter image description here"></a></p>
  
  <p>But the documentation is located in /compute/docs which should not obviously be compatible with /appengine/docs</p>
  
  <p>And here is a graph describing the tunnel, which talks only about GCE, which could exclude GAE :

  <p>So, is GAE compatible with Cloud VPN or is it restricted to GCE only ?</p>
