Hi Praveen, I tried Simple-Gateway and it works. But that is useful only to access VM from Host via its private IP. I don't want to create VM in public VN. I want to create VM in private VN and assign floating IP to VM from public VN. How to do this ? also please explain packet flows ?
What is the difference between Simple-Gateway and Floating IP feature? I could find a doc which explains Simple-Gateway clearly with diagram and i followed it https://techwiki.juniper.net/Documentation/Contrail/Contrail_Controller_Feature_Guide/Configuration/Setting_Up_and_Using_a_Simple_Virtual_Gateway_with_Contrail Looking for similar doc for Floating IP.
