Welcome to the UPnP PortMapper

About

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!

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.

Changes in Version 1.5_beta2

• Added German translation
• Increased timeout for router discovery to 5 seconds

Changes in Version 1.5_beta1

Port mapping presets can now be edited and are stored on the disk.

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, Ubuntu Linux and Windows XP.

The latest Java Version can be downloaded here.

Known issues

• Under Ubuntu Linux it is not possible to retrieve the IP address of the local host, the address must be entered manually.
• The german translation is missing for the current beta version.

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.
