Thanks Ashok Kumaran, I follow your link, but when i associate a Floating IP in new_Ext_net to an instance, Horizon throw an error:
*Error: *External network 4a7f4ca5-a787-4f64-8a4b-22a11f9b55f7 is not reachable from subnet 9c921f72-a60e-4eae-b53f-f3eff3218627. Therefore, cannot associate Port d105d3e7-6702-4ff6-81f8-65fba219bd0b with a Floating IP.
