Forget everything that I've written, I just need to assign 6 VLAN (tagged, coming in from enp2s0) to 6 NICs (untagged to: enp9s1f0, enp9s1f1, enp9s2f0, enp9s2f1, enp10s1f0, enp10s1f1).
If the connections are already tagged as you come into the Proxmox server, then you need only to create interfaces for them in Proxmox (vmbr1, vmbr2, etc). EDIT: if you’re doing PCI passthrough of the physical NICs, ignore this step.
Then, in OPNsense, you just adding the individual interfaces. No need to assign a VLAN inside OPnsense because the traffic is already tagged on the network (per your earlier statement).
Whether or not the managed switch that has tagged each port is also providing VLAN isolation, you’ll simply use the OPNsense firewall to provide isolation, which it does by default. You’ll use it to allow the connections access to the fiber WAN gateway.
I've just edited the original post to make clear that Proxmox has nothing to do in this picture, it just is installed in the same PC where the NICs are. What I need it just assign 6 VLAN (tagged, coming in from enp2s0) to 6 NICs (untagged to: enp9s1f0, enp9s1f1, enp9s2f0, enp9s2f1, enp10s1f0, enp10s1f1).
