[Authentification] Relais Icecast2 vers Shoutcast

Bonjour   ,

je souhaiterais pouvoir connecter un serveur Icecast2 (sur une machine en local -192.168.0.2-) vers un serveur Shoutcast (chez un hébergeur -xxx.112.138.24-port: 4848).

Le problème est qu'il faut paramétrer le serveur Icecast2 en relais, mais également que le serveur Shoutcast accepte le flux de donnée provenant du Icecast2.
Le serveur Shoutcast demande un mot de passe pour pouvoir s'y connecter, et dans le fichier de configuration icecast.xml, aucune donné ne se rapporte a cela.

Ou dois-je indiquer le mot de passe du serveur shoutcast ? (j'ai déjà testé plusieurs configuration, lis plusieurs dizaine de sujet un peu partout, le problème est régulièrement exposé mais aucune réponse précise n'est présente ou suffisement détaillé).  
(Je précise que tous les ports sont ouverts)

             time for listeners that do substantial buffering. However, 

             it also significantly increases latency between the source 

             client and listening client.  For low-latency setups, you 

             might want to disable this. -->

Pour résumer, je cherche donc à ce que la sortie du flux Icecast2 se redirige vers Shoutcast (Musique > Icecast2 (serveur local) > Shoutcast (hébergeur)> Auditeurs)

Merci d'avance a celui ou celle qui pourra me permettre de trouver la solution.
