Added quad-port NIC, no more connectivity?

[cmer]

Hey guys,

I am currently using the motherboard built-in NIC (enp2s0) to on my Proxmox box and everything is working fine. However, the second I plug an additional NIC card (in my case, an HP quad-port 1gbps), I lose in/out connectivity over my built-in NIC.

Am I missing something? Is there something I need to change/configure before adding that additional card?

In case it matters, my goal is to PCI passthrough that quad-port NIC to a pfSense VM.

Thanks in advance!

usually plugging a new NIC in should not change the name of the build in one - that's what predictable interface names ought to be there for.
Sadly sometimes it does not work as expected...

Check the output of `dmesg`, `ip link show` and `lspci -nnk` for hints as to where the problem might be.

In case it matters, my goal is to PCI passthrough that quad-port NIC to a pfSense VM.

check the reference documentation for pci(e) passthrough : https://pve.proxmox.com/pve-docs/chapter-qm.html#qm_pci_passthrough

hope this helps!

Thanks a lot. Turns out, somehow, my NIC name changed after plugging in the new one. I didn't even think this was possible so thanks for pointing me in the right direction.
