The next step is determining if you want your server to be a private server or a public server. A private server is a server that is hidden from the public BeamMP server list and is only joinable by using the direct connect functions in the BeamMP launcher.
In order to connect to a private server, you must navigate to the direct connect tab in your BeamMP server browser and enter your server's IP:PORT. You can find your server IP and Port in your game panel under the "Console" tab. When connecting to your server you can use your numeric IP address or you can use "play.beamhost.net" as an IP address.
A public server on the other hand is much easier to connect to as it will be displayed in the public server list and can be joined by anybody on BeamMP.
Once you decide what style of server you want you can set the "Private" option to true or false.
true=Server Is Private
false=Server Is Public
