Subject: [Rdo-list] Confusion with Floating IPs in RDO Liberty Packstack 3-node setup

I have a 3-node setup using packstack. It went smoothly with no issues.

I created a public subnet with the following command.

neutron subnet-create --name public_subnet --enable_dhcp=False --allocation-pool=start=,end= --gateway= external_network<>

So I should have about 18 usable IP addresses. Perfect.

But I only have 2.

[root at dell-r430-13 ~(keystone_atomic)]# neutron floatingip-list
| id                                   | fixed_ip_address | floating_ip_address | port_id |
| 1c94a153-20d4-43cd-b8c2-4d259975e043 |                  |       |         |
| ad4e0089-2d4d-46dd-a0f2-21b6c854398d |                  |       |         |

I had to create the floating IPs manually with a for loop.

It wasn't hard. I'm just wondering what I did wrong, or if that's something I've just somehow missed every other time.
