Adding second NIC in tight mini ITX case (Antec ISK110 VESA case)



  • Hi kind folks,

    I am trying to build a new pfsense setup in the very small Antec ISK110 VESA case. This is for a firewall at home.

    The motherboard is a Biostar J3060NH Mini-ITX with one onboard NIC and a PCI-E slot (1 x PCI-E x1 2.0 Slot). The motherboard is a "combo" in that the processor ( Intel® Celeron J3060 Dual-core 2.48G) is inbuilt on the motherboard.

    I got an additional TPLink  TG3468 PCI-E network card and it fits the motherboard well.

    However, the PCI-E slot is at the very end of the board, and I am just not able to fit it inside the mini ITX case.

    The options I am thinking are

    1. Really low profile PCI-E x1 network card. Any suggestions?

    2. A kind of extender cable which I can use to maybe place the 2nd NIC elsewhere. What kind of extender should I be looking at?

    3. USB to LAN adaptor. Is this advisable?

    4. Look for another mini itx motherboard with dual NICs. I have had no luck so far. Where I live, they are mighty difficult to come across.



  • I would get this for a ISK 110

    Motherboard: ASRock Z270M-ITX/ac

    That requires him getting a new cpu and ram as well.

    -the case you're using does not allow for any pci/pci-e expansion. It'd require significant modification to the case, to make it work.

    if you have a switch already, you can setup VLANs, it would allow you to use your current setup without having to spend any more money.  Otherwise, I'm afraid you're looking at getting a new case or a new motherboard with associated components.



  • Do not forget to add a low profile cpu cooler to the new kaby lake processor on your shopping list.



  • Thanks folks.

    I have an old Asus RTN13U running dd-wrt, which I think I can configure as a switch with VLANs.

    The regular switch on the network is a D-Link DES-1061D, which is a plain old switch.

    So how does one go about with this VLAN thing. Any pointers?



  • Curious what makes you think that you can get vlans on your RTN13U.

    That's perfect and all you'll need, I'm a big Youtube learner, I'd start with just searching how to setup vlans in pfsense.

    Thanks for the link.

    The RTN13U is already running dd-wrt. So I think it can be configured as a switch (with VLAN). Do correct me if I am wrong.



  • i have zero knowledge of dd-wrt, but you would set up the VLAN on the pfsense system, not the switch. so if dd-wrt allows you to use it as a switch then you should be good



  • Guess you missed the section on switch configuration in the article. Any managed switch will need configuration of vlan membership and vlan port settings for it to work.
