Advanced UDP/TCP Active Port Forwarder
NetworkActiv AUTAPF is an easy-to-use, quick-to-configure 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
- Forward multiple ports simultaneously with rock-solid stability.
- Optionally block IP addresses via an external program or script -- in real-time.
- View real-time data and connection statistics for each port forward.
- View connection events in real-time and or save them automatically to a text file.
- Run without installing, run installed, or run as a system service -- your choice.
- Automatic relative-path technology enables true portability.
- Configure your forwards using a conventional GUI, a Web browser, or both.
- Web interface is password-protected using digest authentication.
- Have program hide in system tray.
- Optionally bounce connections back to client, on same or alternate port.
- Optionally define multiple destinations for UDP port forwards, for relaying datagrams, such as SNMP traps, to multiple servers.
- Bind interfaces via IPv4, IPv6, or MAC address.
- Full support for IPv6, including Scope IDs.
- Optionally save all connection data (UDP or TCP) in real-time to individual files.
- Available in 32 and 64-bit builds, for optimal compatibility and resilience.
- Intelligent interface monitoring system keeps the forwards flowing, even in unstable environments.
At the time of this writing, the current trial is limited only in that there is a periodic nag screen that pauses the forwarding while displayed. Note that these limitations may change at any time without notice.

Aside from those language options built into AUTAPF and available through the language choice dialogue (via the Language->Change menu option), the following language string files are available for download. These are used through the bottom option on the language choice dialogue just referred to. To download, right-click the download link and choose your browser's Save as... option.
- No translations have been procured since the release of the current version.
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 sprung 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 ;(
(A true story by NetworkActiv)
64-bit CPU and operating system are highly recommended, but 32-bit will suffice for basic purposes.
15 MB of available disk space.
16 MB of available RAM. More may be required, depending on number of running port forwards, number of simultaneous sessions, and logging options.
1024x768 or higher screen resolution is highly recommended.
Windows XP/2003/Vista/7/8/8.1 (32 or 64 bit).
Installation requires administrative privileges, but installation is optional.
Internet Explorer version 8.0 and equivalent (or higher) is recommended for the Web-based GUI.
IPv6 support requires that the IPv6 protocol be installed on the system.
Main changes in version 2.0:
- User Account Control (UAC) compatibility for proper support of Windows Vista and higher.
- Improved handling for running as a system service.
- Improved handling for system shutdown.
- Support for IPv6, including automatic handling of scoped addresses.
- Automatic relative path technology for true portability.
- Web-based login for configuring and monitoring port forwards in a Web browser.
- IP filter files are now text-based like the DTFIPF system. Both are now compatible.
- New option to test an IP address against the configured IP range filters.
- Right-clicking PFO headings now allows specific columns quickly to be shown or hidden.
- Now available in 64-bit.
- PFOs now can be copied and pasted, including between program instances.
- Local and remote addresses (and their ports) now can be copied to the clipboard via right-click.
- Version 2.0 can import settings from ASCII or Unicode builds of version 1.0 or 1.1.
- Overall program font-size now can be configured -- in Preferences or on Language dialogue.
- Basic port ranges now can be created automatically via a new tool found in the PFO menu.
- Grossly improved handling for a large number of PFOs.
- Multiple PFOs now can be selected, toggled, copied, and pasted at once.
- New option in Preferences to disable ghost-binding, or binding of interfaces that are unavailable.
- Outbound-local (OL) binding now supports MAC-based binding.
- Grossly improved resolving performance for local and remote addresses.
- New Log Tail technology available through the View menu shows latest log activity, even when file-based logging is disabled.
- Data logging for storing transferred data for each connection or session into its own file.
- PFOs now retain statistics even after they are restarted, such as when interface goes down.
- New parameters for automatic logging, #TCD and #TSD, record total-client-data and total-server-data (in bytes).
- New PFO advanced option: TCP No-Nagle.
- New PFO advanced option: TCP Keep-Alive (OOB).
- UDP multi-destination support with automatic multiplexing.
- Many bugs and glitches were removed.
- Many various other changes and improvements were made.
Main changes in version 1.1.1:
- Can now bind interfaces based on MAC address (for Windows 98 and up).
- Can now bind interfaces based on hostname or other resolvable address.
- Other binding options are now per-PFO (rather than global).
- A few minor, additional improvements.
Main changes in version 1.1:
- Addition of Dynamic Text-File IP Filtering.
- PFOs can now have comments.
Main changes in version 1.0.7:
- A Unicode version is available.
- Fixed the settings-saving glitches.
- A few other minor changes/improvements.
Main changes in version 220.127.116.11:
