It isn’t the FOG , i just want to understand because your problem describe seems the same i.

@george1421

It’s very long to describe all test, but to resume , there is 2 network card one 1GB and 10GB.
There is no issue with 1GB all packet (wireshark) pass.
When you unplug 1GB to 10GB and capture with wireshark , I have this message in log capture > “user aborted the transfert” here “user” is the card 10GB

@george1421

Yes the same hardware except the switch is different.
All packet TFTP in PXE are rejected by the NIC card.
