Hi Ignazio,

I try to change the heat configuration as you suggested, but still my
instance are try to 10.60.60.10.
this is the output :

| 0c34c8b0dcdc459f818c2bab04913039 | RegionOne | keystone     |
identity        | True    | public    | http://10.60.60.10:5000/v3
|
| 8ca42fccdb774f9daf67c95ea61fd006 | RegionOne | keystone     |
identity        | True    | admin     | http://10.60.60.10:35357/v3
|
| 8d0a23730608495980dce151d466a579 | RegionOne | keystone     |
identity        | True    | internal  | http://10.60.60.10:5000/v3
|

testing curl :

@swarm-cluster-wtet5ppc5eqi-primary-master-0 ~]$ curl
http://10.60.60.10:5000/v3
^C
[fedora at swarm-cluster-wtet5ppc5eqi-primary-master-0 ~]$ curl
http://10.61.61.10:5000/v3
