Public bug reported:

Devstack 2015.1, single box.

Trying to get floating ips to work across 2 /24 blocks  (on a /16 subnet)
Localrc:

HOST_IP=10.100.130.8 # public ip of host, 10.100.0.0/16 subnet
FLAT_INTERFACE=eth0
FIXED_RANGE=10.140.129.0/24 # private 
FIXED_NETWORK_SIZE=255
FLOATING_RANGE=10.100.129.0/16 #publicly reachable network for vms, also in 10.100.0.0/16, but only 10.100.129.X block
MULTI_HOST=0
LOGFILE=/opt/stack/logs/stack.sh.log
ADMIN_PASSWORD=*
MYSQL_PASSWORD=*
RABBIT_PASSWORD=*
SERVICE_PASSWORD=*
SERVICE_TOKEN=*

Creating a guest :
assigned ips private=10.140.129.3, 10.100.129.2

On the host itself (ip a l)
    inet 10.100.129.2/32 scope global br100
       valid_lft forever preferred_lft forever


Address is not accessible from the outside (because it's a /32, expected a /16)

Initial pool was created with range 10.100.0.0 - 10.100.255.255 and then
started assigning ips from 10.100.0.1 conflicting with the router, and
also ips were assigned /32

I deleted the pool and created a new one: 10.100.129.0 - 10.100.129.255
but ips are still /32.
