A single segment network is a logically connected nodes operating in a same portion of the network. In a such a network, WFilter must be installed where it can monitor Internet traffic across the network. You may set the monitor mode to "by MAC address" in "Monitoring Settings" of WFilter.

As in Figure 1, local computers connect to the Internet by a router. Under this network, you need to mirror all traffic of the router to WFilter. And the machine with WFilter installed on shall be connected to the monitoring port of the switch.

A broadcasted hub also works, however, as most broadcasted hub only works in 10Mb speed, we recommend you use a port mirroring switch if your internet bandwidth is larger than 4Mb.
