Comment on Basic networking/subnetting question.

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.

    Thank you for the comment.
    
    My threat model in brief is considering an attack on my internal switching infrastructure. Yes, I know that the argument of “if they’re in your network you have other problems to worry about” is valid, and I’m working on it.
    
    I’m educating myself about Lynis and OpenVAS, and I tend to use OpenSCAP when I can to harden the OS I use. I’ve recently started using OpenBSD and will use auditing tools on it too. I still need to figure out how to audit and possibly harden the Qubes OS base but that will come later.
    
    Yes, I do realise that the dumb switch has an OS. And you raise a good point. I’m starting to feel uneasy with my existing netgear dumb switches too. Thank you for raising this, I think a whitebox router build might be the only way.
    
    I’d like to mention that I would use VLANs if I could use them on hardware and software I feel comfortable with. But I cannot. Whitebox build it is, I suppose.
    
    Thanks again for the comment and I’d like to hear any suggestions you have.

  Or a openwrt to make it L3

    True, a commodity all-in-one-box running OpenWRT, or an SBC that supports it would work perfectly, except maybe for a lack of ports

Op specified they have a dumb switch
