I'm making an application which is sending and receiving video and audio through WebRTC using WebView (to kurento media server- but this is not important). When I'm using a home network with normal router, the connection and video is working without problems. The problem is when I'm using a network from my phone (where I'm running an application). What I found there, what is probably some pointer, what can be wrong is:
For ipV4:

Have you any idea, what can be wrong, or where can I look for a problem?
