I have setup a test environment using the "OpenStack Installation Guide for Red Hat Enterprise Linux and CentOS" for Mitaka.

OpenStack Installation Guide for Red Hat Enterprise Linux and CentOS

I chose Option 2 for networking, which supports attaching instances to self-service networks.

Management Network:

Provider Network:

I have create two instances based on the Cirros image. Each Cirros Linux image can ping the other.

I have defined a floating IP address pool using the following commands:

 neutron net-create ext-net --router:external=True Create an external network for the pool.
Neutron subnet-create --allocation-pool start=,end= --gateway --disabled-dhcp est-net

I have create a router connecting "ext-net" to Local Network I chose as the IP address of the Internal Interface.

I have checked out Floating IP and assigned it to a Cirros Linux instance. I am unable to ping anything on the network.

Here is the traceroute from the instance with the floating IP:

Your provider network has a default gateway? Like or Which ever is the default gw for the provider network needs to be added to the router as well.

Also, make sure you modified your security settings and are allowing ICMP and SSH into the network. The ingress ports.
