# Numbus Server documentation

## ⛏️ Configuring Crafty Controller

To access your Minecraft server, **ports** need to be **open on the firewall**. In order to **minimize** the number of open ports and thus reduce **risks**, the numbus-server will only open a necessary number of ports that matches the number of minecraft. **Most people** should set the number of servers to **1** of their favorite version.

These option **only configure networking** and **won't** create the Minecraft server for you. You will have to do it in Crafty's interface.
