Thunderbolt 3 Ethernet Adapters

[spetrillo]

Afternoon all,

I have a HP Prodesk 600 G4 Mini with one NIC. Would love to add a second NIC, and on the back on the unit I have a full fledged Thunderbolt 3 connection. Can I use a Thunderbolt 3 USB C ethernet adapter as my second NIC with OPNsense?

Thanks,
Steve

the usb-c port on the front of the 600g4 us usb 3.1gen2 ( 10gbps ) not tb3 ( 20gbps ) - so tb3 NICs won't work

You would be better off looking at a m.2 format NIC to go either in the wifi slot (2230) or the 2nd storage slot (2280) - you can get proper intel chipset NICs in that format which are well supported

Not on the front. On the rear, in the open slot.

I will look into the other options you mentioned.

Do you have examples? I looked for m..2 NICs some time ago out of interest, and could hardly find ones, especially with an Intel chipset.
The only one I remember is on Amazon: "Kalea Informatique Controllerkarte Mini PCI Express (MiniPCIE) – 1 Port LAN Gigabit Ethernet – Chipsatz Intel 82574"

Yes I found a couple on eBay but most are Realtek. I am going to try the Realtek and see what happens.

This is the one I am going to try: https://www.ebay.com/itm/255460423126?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=255460423126&targetid=1264870805664&device=m&mktype=&googleloc=9004262&poi=&campaignid=14859008593&mkgroupid=130497710760&rlsatarget=pla-1264870805664&abcId=9300678&merchantid=137736496&gclid=Cj0KCQjwvqeUBhCBARIsAOdt45YJIuG37o_Lr-l1wWd5E3E-TXBjU_I-Ik35FlOBHia-llb33cT3xrAaAnEmEALw_wcB

Another manufacturer makes one with an Intel chips etc but it's connected to a low profile PCI bracket. I Sent them a question if they could make it with the end of the one I am going to try. If they do that then all good.

try this - i210 based and you should be able to unscrew the panel mount rj45 from the pci backplane and hack it into the 'configurable slot' cutout on the mini

doh - didn't pay enough attention - it's mPCIe not m.2

if you were really keen you could try it into the m.2 using a suitable mPCIe/m.2 adaptor - Could be fun stuffing this plus the mini-pcie NIC into the available space though

Possibly...

Since I have the open Wifi M.2 slot I am going to use this and see how it operates. I am looking forward to getting a second NIC into my Prodesk 600. I have to buy a 2.5 gig switch to do this though, but I was going to have to do this sooner or later, with Wifi 6e coming.

Sometimes you gotta look closer!!! Here is one with the Intel i210 chipset...woo hoo!

The Kalea one on Amazon seems cheaper:

[spetrillo]

Its mPCI and not available. I am trying to use my Wifi M.2 slot.
