I am looking for an inexpensive small 4 or more port programmable network hub/switch.
Currentlly I am using a Netgear (10BaseT) 4 port hub. This works fine except it does not do exactly what I want it too.
What I need the switch/hub to do is simple. The uplink port will be connected to a backbone. When ever a packet of any type comes in this port I want it to go out all the other ports. When a packet comes in any OTHER port I want it ONLY sent out the uplink port.
In other words, the ports are only allowed to talk too and listen too packets on the uplink port.
