Thank you Bart!
I think I have it all set up almost right now, it is close, but still no cigar.
The OpnSense PC is a VivoPC VM62 https://www.asus.com/Mini-PCs/VivoPC_VM62/
Ethernet NIC is
dmesg | grep Realtek
dmesg | grep RTL
My switch is set up like this
It should be just like Bart wrote, but I have two tagged trunk ports = ports 1 & 2, not just port 1 (I'm planing on reinstalling the IPcop PC with OpnSense and let it use port 2):


I have connected the cables to the switch like this

My OpnSense has these VLANs

NOTE!! -->It works with using VLAN 222 to LAN with this setup. Like this everything works well, all users can surf and so on.

But if I try to change also WAN via VLAN like this

Connection via LAN still works to OpnSense, but WAN never gets any IP from IPS DHCP so nobody can reach Internet. It is like the connection from VLAN666 on re0 don't communicate with ports 6, 7 & 8 on the switch.
