  1. Make your APP keep a long connection with Server

  2. Let server maintain all the connected clients, server will know the ip address and port nunmber

  3. Let server help you to forward the data or you can let server to help setup STUN

Please also refer to STUN (Session Traversal Utilities for NAT)
