if you mean how to join your server in your pc.... you need to port forward your gameserver ports. Game server can be create by client or by tools, example for client. if you create new internet lobby server and you joined your own server there. then that's it, you created your own server and for how people can access your server. you need to port forward just like what i said before. Same as if you create your server by tools on computer server and allow access by port forward or windows firewall with advance settings.
