I used a pair of Raspberry Pi 2s, connected to each other by a pair of IPSec tunnels.</p> <p>This post is related to <a href="http://luispa.com/en/posts/2014-10-05-router-linux/">Linux Router for Movistar</a> and <a href="http://luispa.com/en/posts/2014-10-18-movistar-bajo-demanda/">video on demand</a> with Fullcone NAT on Linux.</p> <br clear="left"/>http://luispa.com/en/posts/2014-10-18-movistar-bajo-demanda/Sat, 18 Oct 2014 00:00:00 +0000http://luispa.com/en/posts/2014-10-18-movistar-bajo-demanda/<img src="http://luispa.com/img/posts/logo-linux-rtsp.svg" alt="Linux router logo" width="150px" height="150px" style="float:left; padding-right:25px" /> <p>The IPTV video streams used by Movistar come in two types: regular channels (Multicast/UDP) and video on demand (Unicast/UDP). In this post I describe what needs to be done on the <a href="http://luispa.com/en/posts/2014-10-05-router-linux/">Linux router for Movistar</a> to make &ldquo;Video on Demand&rdquo; work. They use the <code>RTSP</code> protocol which requires our router to support <strong>Full Cone NAT</strong>.</p> <p>The set-top boxes request videos via RTSP from their control server, but the video is sent from a different server with an unknown IP, so if we do nothing the video traffic will be dropped. Let&rsquo;s see how to solve this.</p> <br clear="left"/>
