View Common Uses of AUTAPF


Advanced UDP/TCP Active Port Forwarder

NetworkActiv AUTAPF is a very easy to use, quick to configure UDP and TCP Windows based port forwarder. AUTAPF is stand-alone and does not require any underlying components, for the port forwarding is done within the program itself. Designed with fault-tolerance and for high-throughput, AUTAPF supports a reliable and responsive network infrastructure.



At the time of this writing, the current trial version is limited in that it cannot be installed as a service during installation and that there is a periodic nag screen that pauses the forwarding while it's 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 server on their second (internal) computer. The second computer accessed the Internet through their primary (gateway) computer via ICS (Internet Connection Sharing). NetworkActiv saw this need and thought 'here is an idea for a new program'. About a month later came about NetworkActiv AUTAPF, a configurable UDP and TCP port forwarder optimized for low lag multiplayer gaming and web-page-serving. Unfortunately, the aformentioned person no longer had an internet connection ;(
