My Setup: The vigor 130 is used as a modem (I can confirm that the modem is working because in my current setup it is also acting as a modem.). I want to install opnsense behind the vigor 130 as a router.
The Problem/Story: For a long time I am trying to get ds-lite (ipv4 to ipv6 transition technology mostly used in Germany.)to work on opnsense. I know that it is not officially supported. However I have read that several people had success nonetheless. However for me it did not work. I already asked in the German Forum and the users there confirmed that in General my configuration for ds-lite is working. We broke it down to the issue that ipv6-only pppoe is not working probably. Therefore I am asking if anyone here has any idea what the problem is. The screenshots of the logs and the configuration can be found in the German post: https://forum.opnsense.org/index.php?topic=22286.0. I am going to try to get a packet capture of the pppoe connection attempt. However if someone has an idea, feel free to help. Any help is appreciated.

I think the issue still stands: historically single stack IPv4 was implemented and then IPv6 dual stack was added. Some of these issues are still in the code and complicated a lot by the use of PPPoE interspersed. It needs to be reworked, but we do not have a clear outline yet.

PS: 21.1.4 goes out today with a patch in the right direction, but still baby steps so to speak: https://github.com/opnsense/core/commit/52d6e4a063

maybe we should re-label it "Use PPPoE link' rather than 'Use IPv4 connectivity', after all if the user is not using v4 then it makes no sense.
-
But the issue is it uses the IPv4 rc.newwan script so without IPv4 it will never work... The name is correct and it works as designed. ;)

The script called be called 'Franco's_nightmare', it would still work, but that doesn't make it correct.
-
Fair point. The stuff needs to go to ppp linkup script at least I think...

Does this mean I just have to wait and there is no comfortable way to fix this?

For now there is no solution, yes. It would help to track a feature request... https://github.com/opnsense/core/issues/new?assignees=&labels=&template=feature_request.md&title=
