  I’d either have to do it in the router (which would need a lot of PCIe network cards which can get expensive + difficult to accommodate enough physical PCIe lanes on consumer hardware) or run it on a switch running a proprietary OS that I can’t control and don’t know what it’s doing underneath.

    Can you elaborate why you think you need much more PCIe lanes? Technically you can do with 1 single LAN port with all your VLANs.

    You configure the VLANs on the router then make a single trunk port to a switch. then have that switch divide the VLANs on the ports you desire. this can be a L2 switch.

      Thanks, but to make that work I would need a managed switch running a proprietary OS can I cannot trust.

        What in the world is “a proprietary OS I cannot trust”. What’s your actual threat model? Have you actually run any risk analyses or code audits against these OSes vs. (i assume) Linux to know for sure that you can trust any give FOSS OS? You do realize there’s still an OS on your dumb switch, right?

        This is a silly reason to not learn to manage your networking hardware.

        Or a openwrt to make it L3

      Op specified they have a dumb switch

    As a heads up, almost all OpenWRT routers function as managed switches with vlan capabilities. Not truly all, but a very good number.

      Thanks, yes I realised that OpenWRT devices can do this
