    Hello! I don't know if this is Proxmox or Mikrotik issue, but I've stuck with this for good. I'm getting VLAN ID from another location inside which are another VLANs, so we have QinQ here. All is delivered to rack cabinet, where Proxmox cluster is running. What I want to do is to strip...

    How to: bond+bridge+vlan in Proxmox 4.x and share a VLAN with your VM guests

    This configuration (perhaps you'll call it a work-around) took me a while to sort out, so hopefully it will save you some time.
