hello I am a beginner to the Openstack world I'm using RDO Icehouse and I am trying to understand why I can't communicate to my VMs over the floating IPs.

I installed the allinone RDO Icehouse on a Centos 6.5 following the Quickstart specific for Neutron over an existing network, this is the link https://openstack.redhat.com/Neutron_with_existing_external_network (https://openstack.redhat.com/Neutron_...)

I think I followed exactly the instructions to the letter. I have assigned a floating IP belonging to my local network but from the Cirros test image I can't ping anything on my LAN and I can't ping or ssh into it either from my computer. I can however ping and ssh directly from the compute node to the VM.

A traceroute dies on the second hop: traceroute to 8.8.8.8 (8.8.8.8), 30 hops max, 46 byte packets 1 host-10-0-0-1.openstacklocal (10.0.0.1) 1.035 ms 0.529 ms 0.086 ms 2 172.168.50.83 (172.168.50.83) 3002.228 ms !H 3003.031 ms !H 3003.905 ms !H

where 10.0.0.1 is the router internal interface on the private subnet, 172.168.50.83 is the floating IP I assigned to the VM

Any help is greatly appreciated thanks
