This project is based on Windows Firewall Notifier (WFN), which can be found at https://github.com/wokhansoft/WFN
WFN started as an "extension" to the embedded Windows firewall, and WFN Lite is a stripped-down version containing only the notification functionality.
Please read the documentation about the features and limitation of WFN and WFN Lite. Especially note that WFN Lite is not a firewall itself; it is only an extension of the Windows Firewall!
WFN Lite is tested on an up-to-date Windows 10 64-bit machine with the latest .NET framework installed. It may run on older set-ups too, but this is not guaranteed.
WFN Lite does not accept donations, however if you feel generous, you can support the 'Mother-project' and head to PayPal.
Thanks to everyone who contributed, and a special thanks to Jérôme Saliba for the awesome original WFN project!
