IPv6 the selling point everyone missed.

My point wasn't to troubleshoot the issue rather to highlight how idiotic Windows default behaviour is if its untagging the traffic rather than ignoring it, particularly as the NIC driver is VLAN aware and I can manually select which VLAN to use, so you'd expect the default of "none" would ignore ALL tagged traffic? I guess its possible this is a driver issue.
The intent wasn't to fix the issue but to understand HOW its getting its fixed IP address from pfSense when surely DHCPv6 can't function if its unable to receive a response from the client? So presumably its using RA which pfSense makes no mention of this being tied to the DHCPv6 static IP list.

I would expect windows if not configured to use VLAN's to ignore the tags rather than ignore the traffic, thanks for confirming your setup. This to me explains why you had the problem you had.

I could understand that if the NIC driver didn't support VLANs, but on Linux if the NIC isn't opted into a VLAN it ignores the traffic, which is obviously necessary if you are using tagged and untagged on the same port. A prime example of that being OpenWRT.

Yeah that would indicate Linux is always VLAN aware, whilst Windows when its disabled just acts dumb and accepts everything regardless of tagging.

Just another thing about the Windows networking stack to hate I guess.
