title: Can't Ping Instances or SSH into Instances from Host
body: <p>I have installed Devstack successfully in Ubuntu 16.04 in a VirtualBox VM.</p>
  <pre><code>enp0s3 :10.6.208.111 
  lo: 127.0.0.1 
  virbr0: 192.168.122.1
  </code></pre>
  <p>I have both default public and private network in my topology network with a router.</p>
  <p>I am not able to ping between my host and the instance created (<code>IP:192.168.101.3</code> and <code>floating IPs: 172.24.4.15</code>). <code>Host IP: 10.6.208.111</code></p>
  <p>Current settings:</p>
  <pre><code>Public Network (public 172.24.4.0/27) 
  Private Network (private 192.168.101.0/24)
  </code></pre>
  <p>I also created a floating IP with the IP address <code>172.24.4.15</code></p>
  <p>I created a router with 2 interfaces: one connects to the public and one connects to the private. I created the VM's in the private network.</p>
  <p>How can I SSH to the instance created and ping it from my host IP?</p>
  <p>Thank you.</p>
