Hello GCE,
Non ce n’est pas lié à mon réseau, si je shut le port de l’eco device sur mon cisco, le broadcast en question n’existe plus.
On voit parfaitement que la MAC de l’écodevice broadcast, en filtrant sur sa mac address :

Je veux bien qu’il cherche des trucs mais quand même je ne vois rien dans la conf avec 192.168.0.0 comme host… 
Dois-je lui faire un hard reset ?
