Please pastebin your iptables output. I suspect the above is actually
the correct and desired behaviour. IIRC, by default, you are not be able
to connect to a VM's private IPs from the compute node itself due to
security group rules manifested as iptables rules on the compute node,
but you *can* from the network node (i.e. the node that is running the
neutron L3 agent) via the network namespace associated with the instance.
