visit ipchicken.com and this will give the modem IP address (one made up example I will use below is 86.114.325.733), enter this into the network stream area of VLC player along with the port number that the streaming uses, (i.e.: 31344 for the pli jade3 image) and it should start to play (you might need to forward port 31344 on your router to view it outside your home network)
once I have the port 31344 forwarded, I can goto any PC anywhere in the world, open VLC and enter the following into the open network stream window and it plays - hxxp://86.114.325.733:31344 (replace the xx with tt)
The port may differ for other images but thats what it is on the version of pli jane 3 I`m running
Have a read here hxxp://openpli.org/wiki/GenericStream (replace xx with tt)
