Hi,

I have deployed the Openstack Icehouse version on Ubuntu 14 and configured neutron-ml2 GRE tunneling network.

I have 1 controller node, 1 compute node and 1 neutron node.

I have configured GRE tunneling network, I have created the external network/router, tenant network/router by following the document successfully. Able to launch the instance in tenant network and external network but the instances are not pinging to external network also not reaching gateway.

And i have noticed that br-tun is not passing any traffic from neutron node to compute node. I'm little confused on this concept, Please help me with some inputs to clear this issue.
