No change is needed, except, perhaps, IP addresses (which you should never hard-code, anyway). Your service part, with its IP address and port, should be visible to Internet, that's it. For example, if you have firewalls on the way, they should be configured to allow the traffic with your protocol or port. Those are detail not related to your code itself.
