Hi, Thanks for your response. I don't see this setting in my nova.conf. Will it be possible for you to describe the complete command of recreating the floating IPs with -interface flag?

Is 'public_interface' in your nova.conf set? Recently we've had similar situation with a customer. Turned out that traffic going from VM's fixed IP to floating IP of another VM on the same physical host never gets to public interface and thus never SNATed, and response never gets back. We fixed it by unsetting 'public_interface' and re-creating floating IPs with --interface=<public_interface> flag. It ensures that all packets from VMs are source-translated, and also that floating IPs are assigned to correct interface. Hope that helps. -- Best regards, Oleg Gelbukh Mirantis Labs On Fri, Oct 25, 2013 at 11:41 PM, Narayanan, Krishnaprasad <naray...@uni-mainz.de<mailto:naray...@uni-mainz.de>> wrote: Hi all, Im my OpenStack setup, i am using nova-network to manage the networks.
