I follow the OpenStack Network (Quantum) Administration Guide and build  an internal network and I want VMs in the private network to access Internet.<div><br></div><div>So I follow the instructions and create a "external network", and the internal VM has a floating ip, but it can not connect to the physical Internet. I guess the external network is still a logical concept, which can not be physical one.</div>

<br></div><div>So is it possible to connect to the Internet in the tunnel mode, should I use the vlan mode? What configurations should I change in the vlan mode?</div><div><br></div><div>thanks all</div>
