javascript - PubNub webrtc only working on local network -


ive asked question before without luck.. im having problems following tutorial https://www.pubnub.com/blog/2014-10-21-building-a-webrtc-video-and-voice-chat-application/ . ive written code , works flawlessly on local network, when try connect remote client(i.e. not on same network) code doesnt work anymore. shows black screen video client should be.

phone.receive(function(session){     session.connected(function(session){         $("#vid-box").append(session.video); //outputs black screen     });      session.ended(function(session) {alert("call ended: "+session.number}); });

ive contacted pubnub unable help. has ideas?

webrtc double nat oh no!

⚠️ turn server not provided ⚠️

make sure not on nat network forwarding. otherwise you'll need turn servers (not provided). turn servers broker network traffic , allow constrained network video conversations. mobile providers basic open routing (non-nat). corporate firewalls have @ least 1 nat.

  • turn streams binary video. needed nated networks not required.
  • stun resolves ip address. peer peer discovery.
  • pubnub sends ip address.

webrtc

stun provides ip address. there nothing in webrtc provide means exchange ip address between connecting clients. pubnub comes in.

sturn versus turn server webrtc
