In a packaged game, can anyone create a server?

Hey so I created a multiplayer project where you can create a server and join a server. When i’m testing it out, I open 2 of the New editor window (PIE). One of them is automatically the server and the other is client 1. When I create the server with the server window it works fine and the second window can join but when I create it with the client it does not work. My question is, when you package a game will this still be an issue or will anyone be considered a server?
