NetworkActiv AUTAPF is a solid yet accessible TCP and UDP port forwarding system for Windows. It keeps the data flowing whenever the networks are ready and efficiently forwards many ports simultaneously. It can be configured both via a graphical user 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. Additional features include bidirectional data manipulation and RESTful (server-mediated) IP filtering. Hosts an open-source plugin interface for maximum extensibility.
What's new in this version:
Added ability to filter client IP addresses using an open-source plugin supporting HTTP (Web) requests -- for RESTful filtering. Added ability to manipulate data as it traverses the port forwards. Resolved a glitch or two.
