This is my topology.

I can't ping neith of the two "interfaces" on int-router (10.0.0.100 for the inside, 10.60.51.116 for the outside) and neither I can ping to 10.60.51.82/83 from my controller node (10.60.51.99). Floating ip's are getting correctly assigned from the pool, as far as I can tell.

[root@bablade02 images]# neutron router-show int-router

admin_state_up - True
distributed - False
external_gateway_info - {"network_id": "0f139549-399d-4032-bd32-70403203ba17", "enable_snat": true, "external_fixed_ips": [{"subnet_id": "80a8ed0c-6491-49f5-ae38-7681d6bafb9b", "ip_address": "10.60.51.116"}]} 
ha - False
id - 19bfba0e-79f6-480b-98dc-5212e4620361
name - int-router
routes -
status - ACTIVE 
tenant_id - 28c26250737f41d69a265523ee6bb1a2

Can you help me sorting this out?

Have you installed the Opensatck environments in a Virtual environment? If. so have you enabled "allow promiscuous " traffic on your virtual switch/interfaces. This is a hypervisor setting.

Check the Openstack install guide

"If you choose to install on VMs, make sure your hypervisor permits promiscuous mode and disables MAC address filtering on the external network."

Hi Sudhir,

no, this is installed on an IBM blade. It's a two-node deployment (Keystone, Glance, Nova, Neutron, Horizon on blade01 and Cinder, Ceilometer on blade02).
