How to create ports
You can open a port by going to the Network section. Here you can open a random port for your server by clicking on the Create Allocation
button.
Make Primary
means that the new port will be used as the primary port to access your server, we do not recommend modifying this.
Why random port?
In most cases, a fixed port number is not necessary, as the port number can be changed in the settings. Minecraft plugins, for example, always have a configuration where the port number can be set.
If you do not have a dedicated IP, more than one client will be on the same IP and specifying the port to open, could generate availability problems.
If you have a dedicated IP and want a specific port, you can open a support ticket and we will give you the specific port you need.
