How to get ipv6 to work ?

    Hi,

    I need to get ipv6 to work, because I need ipv6 connectivity for some of my Docker containers.

    I am trying first to get ipv6 to work on the LE system itself, before trying in the containers. To test this, I am logging into ssh and trying to ping 2620:fe::fe.
    But I can't get that to work at all.

    I have tried every setting in LE connection settings. I have tried to set the ipv6 settings to Auto, 6to4, and manual, with no luck.

    I am dumb with ipv6 addressing. In manual mode, I tried to give it a fixed ipv6 based on the public one my computer on the same network has, I just incremented the last number. I am unsure if this is correct.

    What should I try ? What should I check ?

    Thanks in advance for any answer,

    have a nice day
