Hello, I am trying to perform an allinone deployment with an existing LAN using virtualbox. I have followed the instruction mentioned here: http://openstack.redhat.com/Neutron_with_existing_external_network (http://openstack.redhat.com/Neutron_w...) , only difference is I am using a Grizzly release with Quantum.

I was able to perform the above procedure with Quantum, and I am able to ping and ssh into the created instance using cirros from the allinone deployment. the problem is, I am unable to ping/ssh from any other hosts that is currently located on the LAN (or even my host windows machine). I have set up the appropriate floating IP pool, I even tried to open up the iptables to only have: :quantum-postrouting-bottom - [0:0] -A POSTROUTING -o eth0 -j MASQUERADE :quantum-openvswi-sg-fallback - [0:0] -A FORWARD -i eth0 -j ACCEPT -A FORWARD -o eth0 -j ACCEPT

Tried to enable IP forwarding and tried to put eth0 in promiscuous mode. Neither seem to work.

Please let me know if you need additional information.

Thanks in advance.
