Startup variables and network allocations

Startup

The Startup tab shows your startup command and every variable the game marks as user-editable, such as the server jar name or extra flags. Change a value and press Save, then restart. Variables the game doesn't allow you to edit are read-only.

Network

The Network tab lists the IP addresses and ports assigned to your server. The primary allocation is the one the game binds to and the one players use. Use Make primary to switch to another allocation if your plan includes more than one.

Matching game config

Make sure the port in your game's own config (for Minecraft, server-port in server.properties) matches your primary allocation, otherwise nobody can connect.
