Hi I have proxmox 5.1 running on an old dell PC. Currently it is running 1 ubuntu VM and its working fine. however when I insert a Intel dual port NIC into the PCI-e slot, I can't login or ping the proxmox server anymore ( Ethernet is still connected to the build in Ethernet port) when I remove the network card, everything works as per normal? what am I doing wrong. I want to create a PFsense VM using the Intel network card as WAN and LAN.

lspci -vv | grep Ethernet
shows me 3 available network interfaces 2 intel and 1 realtek
