Webrtc работает нормально на локальной сети. местный но не работает в интернете

Я сделал программу webrtc, которая отлично работает в интрасети, но не работает в Интернете. Я отключил брандмауэр маршрутизатора, теперь не знаю, что не так.

Вот мой код:

<?php
global $db;

if(isset($_REQUEST['room_id'])){
$room_id=$_REQUEST['room_id'];
require_once 'modules/Conferencingrooms/Conferencingroom.php';
$conferencingroom=new  Conferencingroom();
$conferencingroom->retrieve($room_id);
$branch_id=$conferencingroom->branch_id;
}
else{
sugar_die('Error! Access is Denind');
}

?>
<script>
if (window.location.protocol != "https:")
window.location.href = "https:" + window.location.href.substring(window.location.protocol.length);
</script>

<video src="" id="localVideo" style="border:1px red dotted">Patient Video</video>
<video src=""  id="remoteVideo" style="border:1px red dotted">Doctor Video</video>
<script>

var pc;
var callNo = '<?php echo $room_id;?>'; // 0 indicates callNo not initialised yet

var caller = <?php if($branch_id==$current_user->branch_id) echo 'true';else echo 'false'?>;
if (caller) {

$("#ajaxStatusDiv").show();

}

Это версия сигнализации php, в которой комната создается на основе идентификатора комнаты в URL
