Hi Remo, If your talking about this document: http://docs.openstack.org/grizzly/openstack-network/admin/content/use_cases_single_flat.html I think that in that case you don't have something from the logical point of view something like a router. You just have L2 segments so there is no place where NAT can happen and therefore you can not use floating ip notion. In floating ip case practically the framework creates a static NAT between the floating ip and the private ip that the instance receive when boots up.
