Need help configuring restund for reflexive connectivity

Sunspark · March 30, 2020, 4:59pm

Hi,

This is the first time I am trying to get an ICE/TURN server running. It is needed for WebRTC reflexive connectivity in order to establish a peer-to-peer connection instead of having to use a relay server in the middle over the internet. One test module to ensure everything is working correctly is at https://test.webrtc.org/

From what I can determine, the two main used servers are restund and coturn. OpenWrt has restund.

Documentation is sparse and I feel like I am missing something but I'm not sure what.. hoping someone else might know.

When installed restund does not start by default as per the comment in /etc/default/restund because it is waiting for you to finish updating the config file in /etc/restund.conf

To manually start it after your edits, you can type at the terminal prompt: restund /etc/restund.conf

These are the only two documents on the subject I've been able to find:

                 Restund Functionality and Architecture



1.  Introduction

   This document describes the overall functionality and architecture
   of the Restund STUN [RFC5389] server.  The server is designed around
   the principle of a lightweight core using server modules to extend
   its functionality.  First we will have a detailed look at the server
   core.  We will then describe the various modules.


2.  Server Core

   This section gives an overview of the functionality provided by the
   server core.  It describes how the server is configured and defines

My clients are behind the NAT on OpenWrt, it's not clear to me if in the config file for the tcp-listen and udp-listen lines if I'm supposed to enter the WAN IP address, or the OpenWrt IP address, or another address.

Right now with either the wan or router IP address when running it, I get told that the address is in use. I don't know if this means I need to do more work in the firewall or something else or if I am using the wrong IP address.

Would anyone know what I am missing, in order to make the test pass?

Thanks!

Hallo Peter,

did you solved the problem yet? I need stun/turn server on openwrt too...

Best regards

Hi, no I gave up. I don't have enough experience for this setup/testing and the need became less urgent when work started allowing us to use ms teams internally over the vpn tunnel.
