3.9.2 NAT binding
In this menu, you can specify the IP address of the Layer 3 port. This address has to be within the address
range of the external network. After you have configured this setting, the address has to be coupled with
the created NAT rules. To do so, select the NAT name and confirm the entry with the + button. A NAT rule
only becomes active once it has been coupled with the address of the Layer 3 port.

3.10.1 Quality of Service (QoS)
All processes are combined under Quality of Service (QoS) that influence the data flow in the device.
Certain payload data can be treated with priority by being assigned to various priority queues. For example,
real-time data, control data, audio or video data can have priority over file transfers.
The switch supports four different queues that are processed with various priorities (w0 – w3).
