[Crowbar] Floating IPs

I have a block of public IPs, x.y.z.128/25, that I want to use for my test cloud.  I used the following in my floating IP section for the network barclamp:

    "nova_floating": {
      "add_bridge": false,
      "netmask": "255.255.255.128",
      "broadcast": "x.y.z.255",
      "ranges": {
        "host": {
          "end": "x.y.z.240",
          "start": "x.y.z.210"
        }
      },
      "vlan": 300,
      "use_vlan": true,
      "subnet": "x.y.z.128",
      "conduit": "intf1"
    },

But now when I try to assign floating IPs from the dashboard it only lists x.y.z.128 to be assigned, which won't work because my first usable IP is x.y.z.129, the one I've assigned to my router. Do I have my network barclamp misconfigured or possibly have a conflict with my public IP range, which is a part of the same subnet? It's setup as:

    "public": {
      "add_bridge": false,
      "netmask": "255.255.255.128",
      "router": "x.y.z.129",
      "broadcast": "x.y.z.255",
      "router_pref": 5,
      "ranges": {
        "host": {
          "end": "x.y.z.160",
          "start": "x.y.z.130"
        },
        "dhcp": {
          "end": "x.y.z.200",
          "start": "x.y.z.170"
        }
      },
      "vlan": 300,
      "use_vlan": true,
      "subnet": "x.y.z.128",
      "conduit": "intf1"
    },
