17.12 Firewall
Application
You can set up a firewall for the primary network interface of the
control. It can be configured so that incoming network traffic is
blocked and/or a message is displayed, depending on the sender
and the service. The firewall cannot be started for the second
network interface of the control if it is active as the DHCP server.
Once the firewall has been activated, a symbol appears at the
lower right in the taskbar. The symbol changes depending on the
safety level that the firewall was activated with, and informs about
the level of the safety settings:
