[Openstack-operators] Neutron Liberty - Can't ssh or ping thru Floating IP

Hi all;
I think I know what to do in the case of Nova, but with Liberty I installed
Neutron Option 2 networking and I can't seem to get floating IPs to work
properly.   I can create and associate, but ca not SSH or PING thru to the
private net.

This is a basic setup via the Openstack instructions.  The public net /
subnet seem to work just fine.  Can crate a Demo instance on Public and ssh
to it.  But can not create a Demo instance on Private, associate floating
IP, and SSH.

Is the floaging IP port itself blocking?   Demo instance has all the proper
security groups.  Don't think it's the fault of the instance.



Session details

Thanks in advance;
-Chris
