Thank you James. I am looking for an option where I will be having only one public IP and then users outside to cloud will use that IP to connect to the VMs inside the cloud.
For example vm whose local ip is 1.1.1.2 and the public ip for the setup is 192.168.10.11. If a user outside to cloud connect to pot 422 of 192.168.10.11 then it should redirect to 22 port of 1.1.1.2 I would like to know neutron has this feature or not . Regards, Subbareddy.

Instances that do not have a floating IP will be NAT’d to the IP address of the qg interface of the router. This is akin to a PAT on other firewalls. A floating IP is akin to a static 1-to-1 NAT, and takes precedence over the default SNAT behavior. By setting enable_snat to false, your traffic is being forwarded out of the router as the fixed IP of the instance.
