Advanced UDP/TCP Active Port Forwarder

NetworkActiv AUTAPF is an easy-and-quick UDP and TCP port forwarder for Windows. AUTAPF is stand-alone: No third-party components or frameworks are needed. The port forwarding is processed from head to toe within this single app. Another advantage is that AUTAPF sports a dual-mode user interface -- accessible both locally, and through a Web browser. Unlike passive solutions, AUTAPF offers real-time log viewing and connection-specific data logging, letting you keep track of what is happening and when. Designed with fault-tolerance and for high-throughput, AUTAPF supports a reliable and responsive network infrastructure.

Features and Benefits


As of this writing, the current trial is limited only in that there is a periodic trial reminder screen that pauses the forwarding while displayed. Note that these limitations may change at any time without notice.

The AUTAPF story

One day there was a person who needed to run a Quake III Arena server on a second (internal) computer. The second computer accessed the Internet through the primary (gateway) computer via Internet Connection Sharing (ICS). NetworkActiv saw this need and thought, here is an idea for a new program. About a month later sprang NetworkActiv AUTAPF, an extensible UDP and TCP port forwarder optimised for low-lag multiplayer gaming and Web-page serving. Unfortunately, the aformentioned person no longer had an Internet connection ;(
