Hi, I have recently been testing with jails, vnet and netgraph on ESXi - so not Hyper-V - but to make this work I needed to: ngctl msg vmx0: setpromisc 1 ngctl msg vmx0: setautosrc 0 outside of the jail when setting up netgraph (where vmx0 is the "real" NIC that the ng_vlans are part of). and then I had to set the mac address for the ngeth interface that was set to be put into the jail ifconfig ngeth0 ether 02:00:01:02:03:04 Once done, and the jail started, ngeth0 worked as expected. In ESXi, the portgroup that vmx0 is connected to allowed spoofing and promiscuous mode. Paul.
