Hi all,

I'm tackling neutron for a school project. I have a basic understanding of networking components and have worked with Ubuntu a fair amount in the past, but I am having trouble understanding the explanations of the architecture of the physical setup when working with the basic environment. I have a three node setup - one controller, one compute, and one network, and each is configured as specified in the Openstack installation guide for Ubuntu. My issue comes when I try pinging after setting up the interfaces within each node. Currently, I have all three nodes connected to a single switch, which is then connected to a router. I am able to ping between the network and controller nodes, but am unable to ping the compute node from either of the other two, and am unable to ping out to the internet at all. I'm sure there is a simple explanation that I am missing, but any help that anyone could provide would be much appreciated!
