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).
So the PC connected to opnsense is running proxmox for it's OS? Create a bridge for each physical interface, then add a tagged interface to it for the one connected to opnsense; Eg, vmbr2 could have enp2s0.100 and enp9s1f0 as members. Just add .vlanid to the end of the interface name in the bridge settings in proxmox, and don't make the bridges vlan aware. If vmbr0 is vlan aware then just add vmbr0.100 instead of enp2s0.100 With that setup the server will switch packets between the vlans on enp2s0 and the other interfaces. Don't need to put any VMs on the bridges
Will add: this is using the PC like a switch, you're probably better off using an actual switch with vlan configuration instead
That's it, thanks!!! So easy!!! Thanks a lot!
I know that it would be better to use a switch, but I would need a 10Gbps (or 2,5Gbps, do they exists) switch with 2 sfp+ port (1 for Internet connection and the second one for the server). In this way I've just bought the 3 old NIC for 25€ and that's it. I know that they will consume way more than the switch, but how many years do I need to break even?
Well it depends on how much you pay for power and what your pc consumes at idle (or at least idling while doing networking). I’d do an analysis and a graph with excel to make sure. Many old (used) networking components can be had for a steal and will still have many years of use still left in them. Use a kill-a-watt to get an accurate account of idle pc power.
