I just picked up and installed a dual port Intel 2.5GB NIC into my Unraid box. https://www.amazon.com/gp/product/B0BY83FW5H I assumed in Settings -> Network Settings I'd be able to edit the Interface Rules to make the two new NIC ports eth0 and eth1, but so far I'm not having any luck.
I've disabled both onboard NICs in my BIOS, but then when I boot into Unraid one of the onboard NICs is still seen by Unraid and works. 😕 Also, my Interface Rules only offer eth0 and eth2 to change MAC address values, even though Network Settings shows eth0-3. The Interface Rules drop-down menu also only has the choice of the MAC address for eth0 or eth2.
Lastly, my eth1 and eth3 are showing the same MAC address.
All I want is for my two 2.5GBs NICs to be in use, and disable/ignore my two 1GBs NICs. But I'm so completely lost here. Any help would be appreciated.
