Is there software for either Linux or NT that can handle port blocking at high speeds such as switched Fast Ethernet?  I need to filter all traffic out that is not destined for certain ports between two networks.  A dedicated router at these speeds would be two expensive.  What I need is a protocol aware bridge.  Any help is appreciated.
