Open Stack

Hello,
I followed the following guide to install Grizzly release on 3-node setup.
http://docs.openstack.org/grizzly/basic-install/apt/content/basic-install_intro.html

I am stuck at my last issue with Quantum networking (at least that’s what I think).
The VM instance comes up and gets the private IP and the metadata.
Also I have assigned the floating IP to it but am not able to ping either IP except when I use:

ip netns exec qrouter-32f35fb4-f9f1-4817-8818-fff832f73810 ping 50.50.1.3       <- fixed IP – private network
ip netns exec qrouter-32f35fb4-f9f1-4817-8818-fff832f73810 ping 10.24.124.4  <- floating IP – external network

Based on that I think the security rules are okay
The router is tied to the specified tenant and using gateway of the external network.
I  think the issue is routing table or maybe firewall related but not sure how to debug this.

Some details of my environment are below.
Any one have any words of wisdom/guidance?

Thanks,

-Farhan.
