Please note that this project has been migrated from CodePlex, so statistics and releases history are not accurate / complete.
WFN started as an "extension" to the embedded Windows firewall, and offers real time connections monitoring, connections map, bandwidth usage monitoring... and has been made open source a few years ago.
Please read the documentation about the features and limitation of WFN. Especially note that WFN is not a firewall itself!
2018.03.03 - v2.0 beta 3
Head to the releases page if you are interested in trying the latest beta version, and keep in mind, this is work in progress! Read the full description page before downloading!
WFN requires Windows Vista SP2 or later (Windows 7, 8, 8.1, 10...) with Microsoft .NET 4.5.2 or higher. Windows Server 2008 or later are not officially supported, but WFN should work fine on them.
Please do not ask for a Windows XP version, since WFN relies on features introduced with Vista, it would require too much work. Well, now that it is open source, maybe someone will port it but keep in mind there are great alternatives out there. And, well, Windows XP is dead now, time to move on!
