<div>You should be close to the solution.
Looking at your GRE tunnels, I only see a one-to-one tunnel in
between your compute node and your network node (provided your
netnode is 10.10.10.1). Could you please confirm that your
controller is either on the compute node or on the network node ?<br></div></div></blockquote><div><br></div><div>My network node is 10.10.10.1. My controller is an independent node, and not on the 10.10.10.x network (following <a href="http://docs.openstack.org/folsom/basic-install/content/basic-install_requirements.html">this architecture</a> although I have changed the external subnets).<br>
