Dell 7070 Micro Build

[NervousCheesecake]

I've been using a Dell SFF PC with OPNsense running on it for quite a while and love the interface. I recently acquired a Dell 7070 Micro and want to install OPNsense on that machine instead and free up the larger PC as it has a discrete GPU for other things.

I have purchased an m.2 to Ethernet adapter and installed it in the flex and installed OPNsense. OPNsense recognizes the realtek adapter with the updated driver packagein the CLI. The stock NIC is the WAN and the Realtek is the LAN

The issue that I am running into is that no PC connected to the LAN gets an IP address from the server and I cannot ping the DHCP server. I do have a WAN address assigned from my current network.

I'm concerned that it may be a driver issue but I have double checked and the driver package is installed. Do i need to configure OPNsense to use it?

You are connecting the PC directly to the Realtek NIC? If so you may need to try using a crossover cable, not all of the modern cards support auto MDI/MDIx like a switch will. There is also an alternate Realtek driver that you load through the packages section in the GUI, the hard part is getting to that GUI if the port isn't working.

Alternate is to connect a switch to that LAN port, and then connect your computer to the switch and see if it gets a connection. Any cheap 5 port switch should do what you need here. If the light on the switch doesn't light, then you know the card is either defective, or a drive doesn't load.

Second alternate, load a linux live disk and make certain that the m.2 card is really working by connecting it to a network.

Last thought is see if you can connect and configure a USB ethernet adapter, you might be able to use it to get into the GUI and gather more info about that m.2 card.

And if you figure it out, please post the solution, I have a couple of mini-pc that I'd like to try this with, most of these don't need the wifi and an extra wired port would be nice to have.
