title: Gcloud instance can't ping another one
body: <p>I have 2 instances running on Compute engine, although the documentation says that I'm able to ping and establish a communication between these VMs I can't. I've tried the ping with VM name and ipv4 address. I also tried to configure new work-group for both VMs and nothing.</p>
  <p>Here's the link: <a href="https://cloud.google.com/compute/docs/vm-ip-addresses" rel="nofollow noreferrer">https://cloud.google.com/compute/docs/vm-ip-addresses</a></p>
  <blockquote>
  <p>If you are communicating between instances in the same network, you
  can send packets to an instance using the instance name, and the
  network automatically resolves the name to the internal IP address of
  the instance.</p>
  </blockquote>
  <p>My VMs configuration:</p>
  <p>Both are in the same network
