getOutboundAddress returns 0.0.0.0

[judos]

What steps will reproduce the problem?
(pretty unsure, here's what I did: )

1. copy the classes into a new project, changed package name
2. execute main

What is the expected output? What do you see instead?
"Mapping SUCCESSFUL. Waiting "...
The above line is not in the console since
"if (activeGW.addPortMapping(SAMPLE_PORT, SAMPLE_PORT,localAddress.getHostAddress(), "TCP", "test")) {"
in Main returns false.

What version of the product are you using? On what operating system?
"bitletorg-weupnp-weupnp-0.1.2-2-ge3770a1.zip"

Please provide any additional information below.
the getOutboundAddress returns the address wrongly (0.0.0.0). I'm not sure why it doesn't work. Is there maybe a workaround to get the ip?
