Basic procedure
Note
Importing a policy file overwrites all existing firewall rules
When the firewall settings are restored, all of the existing firewall rules are overwritten. You
cannot undo the import of firewall rules via a policy file.
Therefore, back up (export) the existing firewall settings before you import a policy file.
With a command according to the following scheme, you can restore the Windows Firewall
settings from a policy file (.wfw).
To do this, call the prompt as the administrator and first define the save location of the policy
memory, then enter a file path for backing up the policy file.
Alternatively, you can save the commands and the associated parameters in a script or batch
file (Page 70).
