How can I create one private subnet in OpenStack

Question

Hi Guys,

I am working in a project. For that I launched some instances in OpenStack. But I don't want that outside world can connect to my instances but my instance can connect to outside world? How can I implement this?

Thank You

Hi@Hasid,

If you launched all the instances within the same instance than you can use the concept DNAT in your router. You have to add one rule in your system that whoever coming from outside are not able to connect but your instance can connect to the outside world. AWS also works in this way. Just search about DNAT concept. It will solve your problem.

Thank You
