Claim:
1. A network connection status detection system, comprising: a network address translation (NAT) router, serving as a bridge for communicating an intranet with an extranet; a server, installed at the extranet and connected to the NAT router through a network; a network electronic device, installed at the intranet and connected to the NAT router; and a host system, installed at the intranet and connected to the NAT router, and connected to the at least one network electronic device through a connection configuration of the intranet, wherein, when a communication channel is established between the network electronic device and the NAT router, the network electronic device spontaneously sends a connection detection signal to the server, the connection detection signal including NAT port number information that is used for going through the NAT router, and when the server receives the connection detection signal, the server sends a confirmation signal in response to the connection detection signal according to the NAT port number information, and when the network electronic device receives the confirmation signal from the server, an indicator of the network electronic device issues a reminding signal, and wherein when the network electronic device receives the confirmation signal from the server, a webpage or content information is generated by the host system for confirming the network electronic device is connected to the server through the NAT router successfully, the network electronic device sends the connection detection signal to the server periodically in a predetermined time interval to perform a network connection status detection of the network electronic device, when the network electronic device receives the confirmation signal, the reminding signal is observable to the user, and the reminding signal is a light signal, a sound or a combination thereof.
