Description of the Invention (1) Technical Field of the Invention The present invention "a two-way signal transmission device that can penetrate a firewall" aims to provide a communication terminal that can be requested Instant confirmation requires the physical IP address of the communication terminal, that is, the communication terminal is required to send out its entity 1 address, the firewall PORT of the open communication and related network connection information, and the required communication terminal selects the connection authority to request the communication. The device and the required communication terminal can penetrate the firewall for two-way signal transmission to solve the limitation of the firewall causing the network point-to-point connection, which is particularly suitable for real-time image voice communication and digital data transmission between the client host and the server host. [Prior Art] Press, between the general network transmission, the server host that provides the network service will use the firewall shelf to prevent others from accessing the network inside the server host, thereby controlling the data on the network. In and out, the network connected to the external client on one end of the firewall passes the real IP, and the other end connects to the virtual IP of the internal network of the server host, which isolates your internal network from the external network. The firewall becomes The only way to enter your internal network' is therefore any incoming and outgoing data going through the firewall, and then through the firewall to decide whether it can pass, so there is more protection for security. Specifically, the firewall only allows some specific Once the data is passed, whether it is from the outside to the internal network or the internal network to the outside world's data must be cleared by the firewall, and these confirmation procedures are completed by some pre-set security rules and policies. And the firewall manager should also be able to visualize the degree of risk to the extent of security control Adjustment.
