Problems setting up PPPoE connection

[HCTMartijn]

Hello everyone, I'm running into a bit of a problem with my OPNsense and new fiber connection. It looks like whatever I try, I cannot get it to work, it refuses to get an IP address. I've added some attachments showing various settings, but can provide more information if necessary.

What I can find in the log is this:

The gateway says "undefined"

The ONT is connected directly to the NIC, there is no ISP provided device in bridge-mode.
If it helps anyone our ISP is KPN. They use vlan tag 6. The username and password should not matter, as long as they're filled in.

I don't know if this is the correct sub-forum, apologies if not.

VLAN configuration should be performed on the Hyper-V host, not in the guest OS.

Cheers Maurice, I'll check that out in the morning. Also I'm just now noticing that I failed to add the images, so that sucks.

Update 24-10: That was indeed the solution, thanks!
