It is possible to set up a local multiplayer network between two FlightGear instances ''without'' using a [[FGMS|multiplayer server]]. All you need to do is map each I/O port of one instance to the corresponding port(s) of the other instance. | It is possible to set up a local multiplayer network between two FlightGear instances ''without'' using a [[FGMS|multiplayer server]].

|A socket connection requires not only an IP address, but also a port number for each side of the link - imagine a port number like a "mailbox" sitting at the address. This mailbox is used by the communicating processes to send out and receive "messages". Different processes (even when possibly identical programs) will need to use different port numbers when running. Because open ports ({{=}}mailboxes) cannot be shared. | |||
Thus, you need to modify the client-side port settings for each additional instance that you are running on the same machine, and map the output port of one instance to the input port of the other instance (and vice versa). | |||
