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.

If you just want each physical interface on your server to participate in a single VLAN, set the corresponding switch port as an access port in the desired VLAN, and then configure each server interface as a normal untagged interface.

You would only do tagged frames (802.1q trunking) if you wanted to support several VLANs on the switch port.

Yes, but...how do I do that?
