VLAN question (self.selfhosted)

I've finally been connected to a fiber connection 2,5/1Gbps! 🥳 Now I want to share my connection with my neighbor and so I've installed 3 PCIx dual 1GB nic (I'm out of PCIe slots 🤷‍♂️).

The connections comes from my OPNsense to the server (Proxmox) via a 10Gbps fiber connection.

I want OPNsense to take car of firewalling dividing the neighbor networks with VLANs. The OPNsense part is done and working, I need to assign to each of the 6 1Gbps NIC each VLAN.

I've tagged the traffic going into the server via the fiber connection, but now how can I assign each VLAN to each NIC? Thanks!

Edit: Proxmox has nothing to do in the equation, it just happens to be on the same server where the NICs are.

Vmbr0 should be your VLAN aware bridge. You create this in the pve networking dashboard.

Then create vmbr0_101 (where 101 is your vlan). Also create vbmr0_102, and so on.

Assign those vmbr0_xxx to each of the VMs.

If you host all the VM's on the same box, create all the vmbr0_xyz in the pve dash, and in each VM/container>networking assign it.

I don't need to assign VLANs to VMs, I need to assign them to 6 phisical NICs (tha fact that they are installed in the same machine where there is Proxmox is irrelevant).

If Proxmox is already installed on the machine, how are you running OPNSense? If it’s not bare metal, it’s a VM, and if it’s a VM it needs Proxmox’s virtual NICs to be VLAN aware, unless you are doing PCI pass through of the entire network card.

Would they have to be VLAN aware if the switch port was already tagged AND if OP doesn’t care to consider untagged traffic ?

OPNsense is in one PC (and it only works as router/firewall), Proxmox is on another PC with all the NICs and Proxmos and it will also work as switch.
