It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.If this question can be reworded to fit the rules in the help center, please edit the question.
NATting & port forwarding would be as close as it can get; you wouldn't be able to e.g. have a web-server on 3 VPS' on the default http port if they're natted.
As for the "internal IP": like posters in the comment section I don't understand what you're asking.
