I have followed the guide for installing Icehouse on Ubuntu 14.04, but I have not been able to ping the tenant router gateway. I even initialized a VI and assigned it an external IP through neutron but still cant see that either. The attached image is how I have the physical system setup.

From the qrouter I can ping the gateway but that's it:
