  • UDM SE / UDM PRO mit IPv6 PPPoE möglich?

    Hi scope

    First of all You would need the IPv4 connection from Stadtwerke (I’ve never investigated whether this was a Dual Stack og plain IPv4 connection - but the price you mention indicate that it's the same sollution).


    In the setup I’ve made for my friend we didn’t need / want the FritzBox at all (it has been returned to Stadtwerke I believe). You might need the FritzBox if you’re using it for telephone, TV and other services??? - found some posts about this. In this case I can’t help - You would need to setup the FritzBox as a bridge I belive.


    Once You have the IPv4 connection the process should be very straight forward. Best option would probably be to reset your UDM Pro and follow the guided setup. As far as I recall this is how I approached the setup process.


    Screenshot from the tab “Internet”. I left the IPv6 active because I wasn’t sure about the Dual Stack or not, and I haven’t had the time / opportunity to figure it out. Username and Password is the same as you use on your FritzBox. The "Expected ISP Speeds are from the guided setup but as far as I know you can manually enter them (should be acording to your ISP connection).



    In the tab “Networks” I also left the IPv6 configuration - but again, I'm not sure IPv6 is working :-).



    Hope this helps.

    We got my friend’s UDM-SE up and running yesterday. He asked the Stadtwerke to change the type of connection - either to a Dual Stack or a plain IPv4. I’m not sure which type of connection / it’s not clear to me when he refers to the conversation he has had with Stadtwerke. There were no issues whatsoever connecting to the WAN after the type of connection was changed (actually I guided him over the phone). I’ve tried to set to IPv6 as described but I don’t know how to check from off site. My friend has been very busy - so we’ll have a look at IPv6 later if he got a Dual Stack. I’ll let you know.


    Thank you again Hoppel.

    Thank you Hoppel

    My friend will ask about the possibility of dual stack tomorrow. They (Stadtwerke) also mentioned the option to get an IPv4 address for a small monthly fee, which would be a solid solution.


    Yesterday I systematically tried all 12 combinations of

    1. prefix set to 56,62 or 64
    2. DNS servers specified IPv6 address as in FritzBox and no specified DNS server
    3. Global Threat management ON and OFF. But no luck / ip address…

    Advanced IPv6 settings were set according to Unifi’s guide that you are referring to.

    Dear forum

    I am sorry for the intrusion but I hope you are willing to help although my German is poor.

    Ich bin dabei, für meinen Freund in Flensburg ein UDM SE einzurichten. Die Stadtwerke haben ein Modem und eine Fritz!Box als Router zur Verfügung gestellt. Mein Plan war es, die UDM SE als Router zu nutzen und die Fritz!Box komplett wegzulassen.


    Laut Stadtwerke Support brauche ich eine IPv6 PPPoE Verbindung mit einer IPv4 "Anbindung" über DS-lite. In der GUI der UDM SE gibt es aber keine IPv6 PPPoE Option. Hat jemand erfolgreich eine UDM SE über eine IPv6 PPPoE-Verbindung verbunden oder verschwende ich meine Zeit mit dem Versuch, dies zum Laufen zu bringen?


    Ich habe natürlich auch beim Unifi Support und im internationalen Forum nachgefragt, aber ich vermute, dass die User in diesem Forum spezifischeres Wissen über die deutschen Provider und Herausforderungen haben.


    UDM SE-Firmware-Version: 2.3.15

    ISP: Stadtwerke Flensburg / Glasfaser - FTTH

    ISP Modem: Genexis FiberTwist P2420


    Prefix Delegation Size ist auf 56 eingestellt und VLAN ist nicht in Gebrauch (laut ISP Support).

    I am setting up a UDM SE for my friend in Flensburg. Stadtwerke has provided a modem and a Fritz!Box as router. My plan was to use the UDM SE as a router and drop the Fritz!Box completely.


    According to Stadtwerke Support I need at IPv6 PPPoE connection with a IPv4 “anbindung” over DS-lite. But there is no IPv6 PPPoE option in the GUI of the UDM SE. Has anyone successfully connected a UDM SE over a IPv6 PPPoE connection or am I wasting my time trying to get this to work?


    I am of course also asking Unifi Support and on the international forum, but I guess users on this forum has more specific knowledge about the German providers and challenges.
