Abstract
A packet filtering system for use with a host computer implementing a streams sub-system comprises a configuration component for maintaining a collection of configuration parameters based on user input, and a streams interface component for managing bi-directional transmission of packets according to the collection of configuration parameters. The configuration parameters may include sets of authorized port, protocol and address designations. The streams interface component preferably includes corresponding modules for port filtering, protocol filtering and address filtering whereby inbound and outbound packets which are not blocked by any of filtering modules are, respectively, passed upstream and downstream between an associated network device and the stream head. A computerized method for managing bi-directional transmission of packets, as well as a computer-readable medium having executable instructions for managing packet transmission, are also provided.
