4.1.5 firewall
The Windows-firewall is enabled in the delivery state. This protects the device against
many types of network based attacks. KEB has configured the Windows firewall that all
foreseen network connections are allowed. The Control runtime and the HMI runtime
are allowed to open all network ports because for both programs a rule in the firewall
exists.
This is the recommended way to configure a firewall: allow (trusted) programs
to open any port instead of allow ports to be opened by any program.
However, in case of assumption that the firewall blocks desired network communication
there is an easy way to disable the firewall completely for testing. On the desktop you
find a “FirewallDisable” shortcut which does this and also a shortcut for enabling the
firewall again.
The commands need “elevated rights”. Confirm the question from the User Account
