Some Minecraft plugins and setups need an extra port. This is common for Simple Voice Chat, web maps, query tools, and proxy setups.
For voice chat, follow the Simple Voice Chat setup steps.
When a supported plugin or mod offers Configure automatically in its installer, you can choose an unused secondary allocation under Port, or use Assign a new port if available. The panel writes the selected port into that plugin's configuration. The steps below are for assigning a port yourself; you must also enter it in the plugin's config.

Create the extra port
- Open your Minecraft server in the control panel, then open Network.
- Click Create Allocation to add another port to the server. If the button is not available, you may already be using all allowed allocations. You can upgrade your allocation limit from the client area, or submit a support ticket if you are not sure what you need.

- Use the IP address and port from the new allocation in the plugin, mod, or proxy config that asked for an extra port.
- Restart the server after changing the plugin or server config file.
Primary allocations
You normally do not need to click Make Primary for a Minecraft plugin. The primary allocation is your main Minecraft server address, and your panel subdomain points to that primary allocation.
If you do change the primary allocation, restart the server afterwards. You can also change your subdomain if you want to use a different address.
You can remove an unused allocation by clicking the bin icon next to it. If you need a different extra port, remove an unused allocation first, then click Create Allocation again.
