【Abstract】 The design idea and realization of hardware and software of the network physical fire wall are introduced. And the implementing process is given. This physical fire wall can cater to the network demand in cwith speed and transfers rate after fixing debugging and operation and realize four control functions. One PC can connect and separate four networks, which has convenient operation and exact action, and adapts multi network to safe connection physical separator and high efficiency openation.更多还原
