No floating IPs are created by default. You must first create a public network and subnet, defining the IP address range for floating IPs at that time.

source /root/keystonerc_admin
neutron net-create public --router:external
neutron subnet-create public 192.168.1.0/24 --name vlan --enable_dhcp=False --allocation_pool start=192.168.1.57,end=192.168.1.62 --gateway 192.168.1.1 (use your network gateway here - change the IP addresses in the allocation range to match what is available on your network)
neutron router-create router1 (router1 has to be replaced by the name of your router)
neutron router-gateway-set $router_id $vlan_id (use your router id and previous created vlan id)
neutron floatingip-create public (repeat as necessary)
