Hello,

I have a huge problem assigning the same Vlan to the VM I have as a proxmox management. In the current configuration proxmox has VLAN 41, I would like one of the virtual machines to run on the same vlan 41.
When setting VLAN tag 41 in the VM and starting it up, I lose access to proxmox immediately:

This is the network configuration of the proxmox itself:

Port one is the port to the backup network, port two is my backup management port. On port 4 which is on the linux bridge all vlans from the router are passed through.
I know that there is definitely something misconfigured, however, I don't know how to configure it correctly. I found a hint in one of the threads to enable Vlan aware, however this did not help. Can you give me a hint as to what I can do about this?
 
I tested without the vlan tag, and in that case I don't lose access to the proxmox GUI, but the VM has no network access, I can neither access the VM nor ping 8.8.8.8 from the VM nor gateway.
