NetworkActiv AUTAPF is a solid yet accessible TCP and UDP port forwarding system for Windows. It keeps the data flowing whenever the network is ready and efficiently forwards many ports simultaneously. It can be configured both via a Windows-based interface and via a Web browser. It supports real-time, scriptable IP filtering and shows the current data throughput rate for each port forward. It can log connection events, log transferred data to individual files, and hide in the system tray. UDP data can be split multiple directions if needed. Installation is optional, and the program can be pre-configured beforehand -- even via script.
