The majority of the time, webRTC applications use STUN servers.<\/p>\n\n\n\n<p>They are straightforward, quick, and, most importantly, do not generate a lot of loads.<\/p>\n\n\n\n<p>Furthermore, they are only used during connection setup to discover and exchange external host port pairs. <\/p>\n\n\n\n<p>Media will be exchanged directly between participants once the session has been established. STUN is, however, occasionally blocked by <a href=\"https:\/\/cloudkul.com\/blog\/aws-web-application-firewall-waf\/\">firewalls<\/a>.<\/p>\n\n\n\n<p>As a result, when STUN fails, developers must &#8220;turn&#8221; and use a TURN server.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-large-font-size\"><strong>What is a Turn server?<\/strong><\/h2>\n\n\n\n<p>Access to the IP address might be restricted by <a href=\"https:\/\/cloudkul.com\/blog\/aws-web-application-firewall-waf\/\">firewalls<\/a> and secure business settings. It becomes impossible for two networks to find one another without distinctive identifiers.<\/p>\n\n\n\n<p>By acting as an intermediary, TURN servers can be used to solve this issue. A TURN server, in contrast to STUN, stays in the media path after the connection has been made.<\/p>\n\n\n\n<p>We will use coturn, a free open-source implementation of TURN and STUN Server that grew from the rfc5766-turn-server project and includes more advanced capabilities.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1- Run the below command for updating the packages<\/h2>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt-get -y update<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2- Now run the below command for installing the coturn<\/h2>\n\n\n\n<pre class=\"wp-block-preformatted\">sudo apt-get install coturn -y<\/pre>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2023\/01\/image-37.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"514\" src=\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2023\/01\/image-37-1024x514.png\" alt=\"Turn\/Stun server\" class=\"wp-image-13358\"\/><\/a><\/figure>\n\n\n\n<p>Make sure the service is running to confirm it runs the below command<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">service coturn status<\/pre>\n\n\n\n<p>You should get below output<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2023\/01\/image-38.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"423\" src=\"https:\/\/cloudkul.com\/blog\/wp-content\/uploads\/2023\/01\/image-38-1024x423.png\" alt=\"Turn\/Stun server\" class=\"wp-image-13367\"\/><\/a><\/figure>\n\n\n\n<p>To start\/stop the coturn service use the below commands<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">service coturn start\nservice coturn stop\n<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3- Let&#8217;s enable the Turn server in the coturn configuration file.<\/h2>\n\n\n\n<pre class=\"wp-block-preformatted\">vi \/etc\/default\/coturn<\/pre>\n\n\n\n<p>Open the file using the above command and un-comment the last line.
