A gaming machine with a communication multiplexer device that allows communications between the gaming machine and one or more game service servers all within a single network interface is described. The single network interface may be a wireless or wired network interface. The communication multiplexer device converts messages in native communication protocols used by the gaming machine to a network communication protocol such as TCP/IP for transmission over the single wired or wireless network interface. The communication multiplexer is designed such that the gaming machine may receive messages that have been transmitted using the native communication protocols without modifying regulated gaming software on the gaming machine.
