Hi,
I have a very similar problem and hope it's ok to reply to this topic, otherwise I can also open a new one.
So when on 26.7.1 my PPPoE config works fine and the connection comes up. I get an IP from the ISP etc and there is no problem as far as I can see.
But if I'm upgrading to 26.7.5 (I also tried to upgrade to 26.7.4 and 26.7.4_1 before multiple times) the PPPoE always fails. The interfaces are up and if I check the Interface Overview/assignments/etc. everything looks the same for me but I don't get a public IP and the status of the WAN interface on the Dashboard is active but "undefined".
I did some research with AI (in fact Claude, ChatGPT and Gemini) and after I tried all the suggested workarounds the AI always comes to the conclusion this must be a bug.
I'm not sure if this is really true because you know AI always sounds pretty sure about everything but isn't always right and after some research I also read a lot about most problems are more config errors than bugs so I guess this is maybe more my problem.
So from the log I can see that the PPPoE just doesn't work, but I'm not sure why. If I do a diff between 26.7.1 log and 26.7.5 log I can see the order of the log messages regarding the WAN interface and PPPoE is a little different but everything happens at the same second. For the AI this is the root cause as the order has to be different and this is a key problem for my config. But as I already mentioned I'm not really sure about this.
Another potential problem according to the AI is that I have 2 10G interfaces for internal traffic and the WAN interface is only a 1G interface. The AI tells me this is a big problem as the 10G interfaces are seen as priority interfaces and the OPNSense tries to connect via those interfaces instead of the 10G which then fails. But I can't see any hint of that in the log files.
I tried to follow the How To Guide about PPPoE over VLAN but it's already 5 years old and I'm not sure if this is still correct after all those years.
Maybe someone can help me, because I now spent so many hours on that problem that I don't know what options are left to solve this issue.
Many thanks in advance.
