UPnP PortMapper Homepage

The UPnP PortMapper is an easy to use program that manages the port mappings (port forwarding) of a UPnP enabled internet gateway device (router) in the local network. You can easily view, add and remove port mappings.

Using port forwarding, it is possible to access servers (SSH, Web, Game servers, ...) running in a private network from the internet. Port mappings can be configured using the web administration interface of a router, but using the UPnP PortMapper is much more convenient: Just create a new preset or select an existing preset and click one button to add a port mapping for your current computer, the IP address is retrieved automatically!

The interface is written in English and German. PortMapper automatically selects the language according your operating system.

Supported operating systems

The UPnP PortMapper is written in Java, so that it should run on any operating system that supports Java. It was tested under

Mac OS X
Linux (Ubuntu)
Windows XP and Vista

Known issues

Under Ubuntu Linux it is not possible to retrieve the IP address of the local host, the address must be entered manually.

Supported Routers

The UPnP PortMapper uses the UPNPLib to access the router. So all UPnP enabled routers should be supported. UPnP is activated by default in many routers. If it is not activated, you can switch it on using the routers administration interface.

The router Speedport W700V is not supported as it does not have UPnP built in.

Version history

Changes in Version 1.9.4 (26.06.2011)

Minor improvements and bugfixes.

Changes in Version 1.9 (20.12.2010)

Important: PortMapper now requires Java 6.0 or later.
About dialog and preferences entries in application menu now work as expected under Mac OS X.
Fixed bug 3017355: The wrong port mapping was deleted when the table is sorted.
Fixed bug 3041853: The protocol of a port mapping preset was not stored correctly.

Changes in Version 1.7

If more than one router is found when connecting, the user will be asked to choose one.
Now it is possible to add a range of ports to a preset. This is especially useful when creating a port forwarding for passive ftp.
Minor bugfix: saving presets without a name or without any ports is not possible any more.

Changes in Version 1.6

The UPnP library weupnp was integrated additionally to SBBI UPNPLib. If your router was not supported by the old library, try the new one!

By default, SBBI UPNPLib is used. You can switch to weupnp using the settings dialog. The settings window The new setting will be active when the Connect button is clicked the next time.

Please tell the guys at weupnp, if your combination of operating system and router works with weupnp. As weunpn is still maintained, there is a possibility that problems will be resolved in future versions :-)

Changes in Version 1.5 final

Fixed encoding problem with German and Norwegian translation
If a directory named PortMapperConf exists in the current working directory, it is used to read and store the configuration files. This is useful when using PortMapper as a portable application.
The default configuration directory can be overwritten using the system property portmapper.config.dir.
Added settings dialog with the following options:
- Use entity encoding for port mapping names (needed for some routers)
- Log level of port mapper
Getting the IP of localhost should work under Ubuntu now thanks to a patch by Dominic (technonotice).
Windows can be closed by typing the ESC key.
