Hi,
Is it possible to do:

How to transport vlan 300-330 using ISP vlan 102 to routerboard-2?
I have been blown away for a few days and miracles are coming out…But not work correctly
just google it.
Look at https://wiki.mikrotik.com/wiki/Manual:Interface/VLAN#Q-in-Q
Are you sure the transport layer (the “cloud” in your picture) doesn’t strip the extra vlan tags?
