Hello, I did try running the PJNATH ICE demo across the internet. I launched one instance as offerer and another as answerer on another machine. They have only private IP addresses starting as 192.*.*.*. Is it a must that there is a need for STUN and TURN server for testing them. Please advise. Thanks & Regards Kiran -------------- next part -------------- An HTML attachment was scrubbed...
