Groups
The software supports complex rules. A complex rule refers to multiple IP and MAC addresses, including non-contiguous IP ranges. To create a complex rule you need to define an address group first. To do so, choose Tools - Groups from the main menu.
For instance, if you want to shape bandwidth from both networks 10.0.0.x and 10.0.5.x with a single rule, the group may look like this:

Once a group is defined, you can use it in a rule:

Group entries can be sourced from a text file that contains one MAC address, IP address or IP address range per line:

It is also possible to populate a group from the geolocation databases if you need to filter traffic by country.
