@sebastian-roth I looked up “MAC Passthrough” here is what I am facing. we have and are getting more HP PROBOOK x360 435 G8, we have to use USB-C>RJ45. when I PXE boot iPXE see the SYSTEMS MAC but once connected to FOG and I register it see the DONGLES MAC. also here are the errors that I see when registering.

Hello all I have FOG 1.5.9 Running on Ubuntu Server 20.04.4. I am able to PXE boot the client to the fog and when I attempt to Quick/Full register the host it seems to work as I see it in the host list of the web GUI, however when the client reboots back into fog it still states “Host is NOT registered” also in the beginning of the registration it get “unknow hardware” and a few ACPI errors
