Can I pass 802.1q (VLAN tagged) through a VPN Tincin HUB/Switchmode?

[Ramses II]

Hi again,

I have changed both routers by two servers with CentOS linux and two
physical interfaces (eth0 and eth1).

I have connected both servers by the eth1 interface.

I have created a bridge and I have added the tap0 and the eth0 interface.

Each eth0 interface was connect to a trunk port (802.1q) of a switch.

I have connected a PC to a untagged port (VLAN5) of one of the switches.

I can see the Mac Address of this PC in the trunk port of the other switch
but is asociated to the VLAN1 (Default).

I have captured the traffic of the eth0 interface of the server that is
connected to the trunk interface of the same switch tha is connected the PC
and not show me the VLAN ID:
