How to make my server online?

So i just finished setting up a server on a windows VPS, the problem is wanted to test & play it on a different machine (my personal computer) instead on the vps. So i'm wondering how to make it ONLINE so i can play it on different pc.

PS: Im newbie so if there's anything you can tell me or suggest, please feel free to do so i'll gladly appreciate it.

Thanks!
