Hi,
I found this old thread:
http://forum.mikrotik.com/t/simple-miktorik-proxmox-vlan-config/128173/1
I re-created pretty much the same setup in a Virtual Environment (GNS3, Proxmox, and a Windows VM on VMware workstation) for learning and practicing purposes.
Everything seems to be working as expected. I saw that the VLAN filtering is disabled in the working.rsc posted by OP.
What is the difference between having it enabled or disabled in this case?
Thanks
