General information on the operating principle of the Windows Firewall

Windows Firewall rules are structured as follows:
● The firewall rules are divided into Inbound Rules and Outbound Rules.
● Each firewall rule is valid for one or several network profiles (Profiles).
Each network connection in Windows is assigned to a specific network profile. In the factory
settings state of the PC system, both the plant network ("Local Area Connection") and the
company network ("Local Area Connection 2") have the network profile "Public".
● Some firewall rules are already assigned to so-called "Groups". As a result, you can more
easily activate or deactivate specific related network functionalities (e.g. file and printer
release).
● To ensure that the compatibility with Windows XP systems exists in the network, the
Windows XP Firewall settings still exist in Windows 7 in the "Local Group Policy Editor"
under "Computer Configuration > Administrative Templates > Network > Network
Connections > Windows Firewall".
If you make changes at this point, the settings take effect in addition to the settings of the
Windows 7 Firewall. Conflicts can occur if the configuration is erroneous. Do not make any
changes to the Windows XP settings if there are no Windows XP systems in your network.
You can make the Windows Firewall settings both via the Control Panel and via the prompt or
script/batch files. The use of script/batch files is particularly recommended for series
commissioning. Alternatively, for series commissioning, you can make all of the Windows
Firewall settings on an individual PC system, save these settings, and apply them on other
devices (Page 90).
