Opnsense VM in Proxmox QEMU error every time I enter a VLAN tag

[Duke-FL]

I have Opnsense in a VM in Proxmox.
The VM runs fine WITHOUT any VLAN tags but, I need to enter a VLAN tag and I get a QEMU error exit code 1.
I have tried to enable QEMU in the options tab of the VM and tried to load QEMU into the VM itself which I cant seem to do.
There are other VM's running on my system with QEMU but, they are Debian or Ubuntu VM's.
Any ideas how I can get QEMU into Opnsense so I can add the needed VLAN tags?

Thank You,

Can you post the output of the task log when starting the VM?

Thanks for your reply...
I attached what info I could find.

Please Note:
enxaa81173088e9 is my USB LTE modem
enp6s0f0 and enp6s0f1 are two RJ45 ports on a PCI card
enp3s0 is the built in RJ45 on my motherboard (which I'm not using at the moment)

It sounds so easy but it's not.
The internet comes in through my USB LTE modem and goes through Opnsense and passed out the two RJ45's on the PCI card.

Thanks for any help,

The issue here is that enxaa81173088e9 has 15 characters, which is the maximum for a network interface. If you now add a VLAN Tag it tries to create the interface with name enxaa81173088e9.101- which is too long. You will need to rename your interface before being able to use it [1].
