Problème d'accès réseau Ethernet

Hello la communauté,


Depuis quelques semaines, je rencontre un problème très étrange avec mon MacBook Pro 13". Certaines IP de mon réseau privé ne sont plus accessibles que via la connexion wifi. Dès lors que je branche le câble ethernet, je perds l'accès à ces IP.


J'ai constaté le problèmes avec les IP de mes VM (hyperviseur ESXi inclus) uniquement. Les autres équipements IP de mon réseau sont tout à fait joignables. Par ailleurs, l'accès à internet fonctionne aussi très bien.


Du coup, j'ai essayé avec le MacBook de ma fille (aussi sous macOS Sierra 10.12.3). Elle n'a pas du tout le problème. Cela marche aussi très bien avec mon iPhone. Je ne pense donc pas que cela vienne de mon réseau.


Afin de planter le décors complètement, je vous soumets mes tests (reproductibles à souhait, malheureusement) :


Via connection Ethernet :

Je précise que mon routeur coeur de réseau est un FortiGate 60D, que mes switchs sont des HPE 1910, que mes bornes WiFi sont des Ubiquity UAP (en AP bridgé, pas de routage LAN/WiFi).


Evidemment, je ne peux pas me déplacer en Apple Store pour montrer mon problème à un Genius... Je fais donc appel à la communauté ;-)


Merci d'avance de pour votre aide afin que je puisse comprendre ce qu'il se passe et comment résoudre mon problème.
