Proof of concept to extend my home network to a remote site through the internet, from where I could consume Movistar’s IPTV services. I used a pair of Raspberry Pi 2s, connected to each other by a pair of IPSec tunnels. This post is related to Linux Router for Movistar and video on demand with Fullcone NAT on Linux. …
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 Linux router for Movistar to make “Video on Demand” work. They use the RTSP protocol which requires our router to support Full Cone NAT. 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’s see how to solve this. …
