The invention provides a network filtering service system and method. The system comprises terminal equipment, a gateway, a filtering server and an application server; the gateway presets source address-based filtering configuration information pushed by the filtering server, and judges whether the source address of the received data packet falls into the filtering configuration information or not; the filtering server is used for receiving the data packet forwarded by the gateway, identifying a source address of the data packet, and filtering the data packet based on a preset source address filtering rule; and the application server performs related service processing based on the filtered data packet. According to the invention, the filtering configuration information based on the sourceaddress pushed by the filtering server is preset in the gateway; and address conversion is not carried out on the data packet receiving the specified source address according to the filtering configuration information, so that the filtering server can filter the data packet based on the filtering rule of the source address, and the problem that a traditional gateway cannot be matched with a filter based on the source address is solved.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a network filtering service system and method. Background technique [0002] The Internet satisfies the supreme realm of "fast" and "unrestricted" that people have been pursuing for thousands of years, breaks through time and space, and realizes people's dream of freedom. It fits the original nature of people, and the degree of "freedom" achieved exceeds people's imagination. The openness of the Internet has allowed people to enjoy the freedom of unfettered access to various information, release of speech, but it has also brought about many information security problems. [0003] At present, in order to solve the problem of information security, filters are usually set up at the network boundary to filter information. Specifically, it can be determined whether to allow data packets to pass through according to the source address, destination address, port number, p...
