Setting up Allocations
An allocation is an IP address and port combination that you assign to a server. It's how players connect to their game server - the allocation determines what address and port appear in the panel.
To create allocations, go to Admin → Nodes, click your node, then open the Allocations tab.

Click Create and a popup will appear:
IP address: Use the public IP of the node's network interface. To find it, run hostname -I | awk '{print $1}' on the node, or ip addr | grep "inet " to see all interfaces. You can also use 0.0.0.0 to bind all available interfaces.
TIP
You can use 127.0.0.1 for allocations if you want the server to be accessible only from the same machine. This is useful for locally hosted services that shouldn't be exposed to the internet.
IP Alias: An optional display name shown to users in the panel instead of the raw IP. Useful if you're behind NAT and don't want to expose the internal address.
Port Ranges: A single port (10000) or a range (10000-11000). These are the ports players use to connect.
Fill in the fields and click Create. The allocations are now available to assign to servers.
