If you're looking for more information on how to allocate specific ports to certain products/orders on WHMCS, check this guide: Port Allocation

To deploy game servers, you need to allocate IP and port combinations to your nodes; we refer to these as "allocations". Adding allocations is done on the node page - under the "Allocation" tab.

Type hostname -I | awk '{print $1}' to find the IP to be used for the allocation. Alternatively, you can type ip addr | grep "inet " to see all your available interfaces and IP addresses. Do not use 127.0.0.1 for allocations, as it would make the server unavailable to anyone. An exception is Minecraft servers behind the proxy.
