How Do I Allow People to Join My BeamMP Server?

Is there any way to allow people to join your BeamMP server without forwarding the port? How do the servers on the list in Beamng show up there? Are they forwarded?

there should be a file named "ServerConfig.TOML, open it in Notepad (or whatever u want), And search for “Private = True”, you want to set True to False, and it should make the server show up on the server list, keep in mind though that if you are the one running the server, you need to join through port.
