1. A network control device, comprising:
- a first network port, connected to a main computer;
a second network port, connected to an electronic device via a network;
a third network port, electrically connected to a target device; and
a processing unit, electrically connected to the first network port, the second network port and the third network port, the processing unit controlling the bidirectional transmission between the first network port and the third network port, the processing unit controlling the bidirectional transmission between the second network port and the third network port, and the processing unit controlling the unidirectional transmission from the first network port to the third network port.

Abstract
A network control device, the network control system and the method of the remote device, the control method comprises of the next steps. A bridge device judges the destination of the packages. If the destination of the package from the second network port is the third network port, the bridge drops the packages. If the destination of the package from the first network port is the third network port, the bridge device merge the operate command according to the packages.
