Fresh install of Proxmox 7.2-7. I have 1 onboard nic and 1 10gig PCI nic. The interfaces show up just find as enp5s0 and enp6s0. I created a bridge on enp5s0 for the mgmt at 10.10.30.7 and then I created a bridge on enp6s0 for all of the data. I can ping all of the sub interfaces on the 10gig card just fine and I can ping out on the sub interfaces but only to their gateways. Also if I shut off the mgmt interface I lose connectivity to the 10gig card. Let me know what outputs I can provide or questions I can answer. I can say I had this working with out issue on a 4x 1 gig card.
