Abstract
The system for content filtering includes at least one content server that stores content. The system also includes at least one client computer configured to transmit a request for the content to the at least one content server. The request contains an address of the content server and a port number associated with such a request for the content. A gateway is coupled to the at least one client computer. The gateway is configured to receive and renumber the request with a new rarely used port number associated with a filter privilege of a user of the at least one client computer. The system also includes a content filtering server, configured to block restricted content based on the filter privilege. Finally, a switch is coupled to the gateway, the content filtering server, and the content server. The switch is configured to listen for the request on the rarely used port number and to redirect the request to the content filtering server.
