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:
Icon Meaning
Firewall protection does not yet exist
although configured according to the
configuration. This can happen, for example,
if PC names for which there are no
equivalent IP addresses as yet were used in
the configuration.
Firewall active with medium security level
Firewall active with high safety level. (All
services except for the SSH are blocked)
Have the standard settings checked by your network
specialist and change them if necessary.
The settings in the additional tab
SSH settings
are in
preparation for future enhancements and currently
have no function.
