ich habe vor kurzem meinen Telekom-Anschluss bereitgestellt bekommen (VDSL 100), dazu einen Speedport Smart 2 (Firmware 050136.3.0.025.0 = aktuell) erhalten.
Nun versuche ich meinen 1781AW (Ver. 10.12.0292RU6 (07.03.2018)) so zu konfigurieren, dass er IPv4 (NAT) und IPv6 zum Speedport routet/weiterleitet. IPv4 funktioniert ohne Probleme. Mit IPv6 habe ich meine Probleme :-/
Folgendes soll realisiert werden:
Internet <> DTAG <> Speedport via DSL <> 1781AW <> LAN
Der Speedport erhält eine IPv4 / IPv6 Adresse und ein IPv6 Subnet.
Im Netz des Speedport funktioniert IPv6 problemlos. Auf dem 1781AW funktioniert IPv6 problemlos.
Im Netz des 1781AW funktioniert IPv6 nicht. Es scheint, als würde der 1781AW IPv6 nicht routen.
Zur Konfiguration:
- Via Router Advertisements erhalten Clients am 1781AW alle Adressen (Gateway, DNS, IP: siehe Bild)
- Ping Client <> 1781AW funktioniert.
- Ping Client <> ipv6.google.com funktioniert nicht.
- Ping 1781AW <> ipv6.google.com funktioniert.

Die fd2a kommen vom 1781AW.
