Ich gebe Ihnen eine kleine Beschreibung des Netzwerks Struktur und was Ich mag zu tun ist und warum! Leider bietet mein ISP (einer der besten in Italien) IPv6 an, aber nur zum Navigieren. Wenn Sie versuchen, einen Dienst (IP-Kamera, Remotedesktop oder was sonst) über IPv6 zu erreichen, kann der ISP den Datenverkehr einfach nicht blockieren Router. Ich konnte den Router des ISP nicht wechseln, da ich die FTTH-Technologie habe und der ISP die technischen Details für die Konverter-Glasfaser nicht zu Ethernet freigibt. Also probiere ich mit der Lösung, die Sie im Bild sehen können, verwende IPv6 / IPv4 vom ISP für die Navigation und einen Hurricane Electric-Tunnel, um von außen erreichbar zu sein.
Das einzige Problem, auf das ich beim Erreichen meines Ziels gestoßen bin, ist, dass der NAS erst mit der Außenwelt kommuniziert, nachdem ich eine Traceroute durchgeführt habe. Danach funktioniert alles einwandfrei, bis eine Verbindung aktiv bleibt. nach einer weile keine kommunikation im he tunnel, wieder scheint die verbindung unterbrochen und nicht zu kommunizieren, nach traceroute wieder ok!
Ich habe wirklich keine Ahnung, was dieses Problem verursachen könnte, ist mir fremd :(

Der HE-Support sagt, dass möglicherweise das Protokoll die Ursache für dieses spezielle Problem sein könnte. Jetzt versuche ich, es beim ISP zu bestätigen und festzustellen, ob das Problem durch die beiden von mir konfigurierten Tunnel verursacht wird.
