Hi everyone

My mother board has 2 embedded Nics.
I want to utilize the 10 gig for my lan & 2.5 for the wan.
Installed proxmox, everything works.
I enabled iommu in the bios. Everything worked as expected.
When adding my 1st VM as opnsense. & Assigned it to my 2.5 gig port I lost the USB ports & the 10gig which had has connectivity to dropped.
It will only enable once I re enable iommu.
Would appreciate if someone can assist.
This for a home Lab.
