I am using hypervisor as KVM and have one server to host Openstack services. I want to access my cloud server and instances(via floating IPs).

Because of the network limitations I am not able to create bridge network. So I had to go with NAT, but with NAT, since the IP is different than host, I can not have external access to server and dashboard. So far, I could not find a solution to work around. I wonder if it is possible to modify the IP mapped by NAT, or using mapped address instead of host address as installing Openstack?

The problem was with the nested virtualisation(since OpenStack uses its own hypervisor). I could overcome this issue as enabling hypervisor(KVM in my case) for nested virtualisation. And after creating bridge interfaces over ethernet interface, I was able to use NAT'ed network into KVM as public network for the VMs in OpenStack.
