VDSL/PPPoE keine Verbindung mit XG 17.5.10 und LANCOM R883VAW

JuergenB

Hallo,

ich versuche mit einer XG 17.5.10 (unter VMware) und einem LANCOM Router eine VDSL Verbindung herzustellen.
Der LANCOM läuft im Bridge Mode, die XG wird über ein NIC Interface mit ETH1 mit dem LANCOM verbunden und der LANCOM hängt am VDSL.

Der LANCOM als Router läuft am VDSL einwandfrei.

Jetzt soll der LANCOM als Modem eingesetzt werden.

Jedoch kommt keine Verbindung über PPPoE zustande, ich habe mehrfach den LANCOM konfiguriert und auch die XG konfiguriert.

Nach einigem hin und her habe ich Dank des LANCOM Forums zwei Traces gemacht, 1x vom Bridge Modem und 1x vom LAN Interface des LANCOM (hier hängt die XG).

Den Logs nach wird auf der Bridge und dem ETH1 des LANCOM ein PADI/PADO durchgeführt, aber die XG kommt mit den Daten nicht zurecht oder führt keine Einwahl durch.

Kann jemand die Logs einsehen, es scheint so, das Bridge Modem kommt mit einer PRIO 6 zurück, die XG sendet ein PRIO 0.

Beide verwendet auch das VDSL Tag 7.

Und bitte, keine Antworten der Art (Warum ein LANCOM, gibt billigere Lösungen oder Warum eine XG, der LANCOM hat doch schon alles).
Oder, warum nicht beim Hersteller nachfragen (Da bekommt man zeitnah keine Antwort, hatte da letztes Jahr Wartezeiten von 3-4 Wochen).
Ich will mit einer XG Erfahrungen sammeln UND auch mit LANCOM Routern ...

Gruß

Jürgen

    Perform a tcpdump on your WAN Port of XG, filter the PADO packets and try to find the reason in Wireshark. Should be easy there.

    Thanks,

    i have a second SG210 with 17.5.10 and a Zyxel Modem setup, this works fine.
    I verified the traces on the Zyxel Setup with the LANCOM traces.

    I used the same PPPoE Settings like the Zyxel setup.

    I will try to get some tcpdump with the LANCOM solution today.

    Hello LuCar Toni,

    i got some tcpdumps from XG and LANCOM Router.

    For me it looks, like the XG is not answering the PADO pakets and keeps on asking with PADI?

    I tried your recommendations and read the link.

    Can you check the trace?

    Thanks in advance.
