Basically, you need a virtual router to connect from you LAN to OpenStack private network.

I think, you don't need a Floating IP exactly on each instance. Only a virtual router, then you can create a static route on each machine in you LAN, for example:

ip route add 10.0.0.0/8 via 192.168.1.100 dev em1

Good Luck!

Answer 2

This IP is a private one, by default, when you deploy a new instance it is deployed with a private IP.

If you want to have a public IP, you need to create a floating IP for your project and afterward, you should assign one IP from this pool to the server instance that you have created previously.

After that you could access to your server instance without any problem.

I hope that it could help you.
