10.4 Firewall
Application
The control enables you to set up a firewall for the primary network
interface of the control, and a sandbox if needed. You can configure
it 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 secondary network interface of
the control, i.e. the machine network.
If you activate the firewall, the control displays the icon at the bottom
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:
Icon Meaning
Firewall protection does not yet exist although it
has been activated according to the configuration.
This can happen, for example, if a dynamic IP
address is used in the network interface configu-
ration, but the DHCP server has not yet assigned
such an address.
