Bonjour,

j'ai remarqué que le log du parefeu de ma Bbox2 est constamment rempli de messages de ce type :

Cette adresse 192.168.182.1 ne fait pas partie de mon réseau local, ai-je des raisons de m'inquiéter ou pas du tout? Ce genre de message apparaît 24h/24 7j/7 dans mon log.

Merci pour vos réponses

Une machine (windows) avec une IP fixe...

Le port 1900 est le port de découverte du SSDP de windows pour les périphériques upnp...

Regarde si dans la famille personne n'a ajouté un Pc windows 8 qui vient d'ailleurs...

je m'édites, car 192.168.182.x, c'est le réseaux FON ou VOOFREE avant authentication...

donc un de tes PC s'est connecter sur le FON/VOOFREE puis, rejeter s'est connecter sur ton WiFi... (avec la même ip, Windows est parfois idiot)

regarde les mac adresses si cela ne te dis rien...

C'est étonnant toutes les machines de mon réseau local sont en IP fixe de type 192.168.1.x.
Il y a 2 tablettes, 2 PC (1 Windows 7 et 1 XP) et une XBOX.
Je ne sais vraiment pas d'où elle vient cette adresse IP personne n'utilise FON ici et le DHCP est désactivé.
