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.
Added Cling upnp library (http://4thline.org/projects/cling/) that may solve problems with some routers. Cling is now default, please test it and report any problems.
Restructured command line interface
