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.

Hi,
I am trying to use ng_vlan on Hyper-V to deploy vnet jails.
The "Enable MAC address Spoofing" setting on the Hyper-V host is enabled.
However when I try to use ng_vlan I am not able to reach the jail.
If I change this to if_vlan instead everything works fine.
Is there something that creating a VLAN using ifconfig does that ng_vlan
does not.
The same setup works well on VMware ESXi, Xen and KVM.
I am not sure if this is relevant to my issue but the hn1 devices sysrc's
changes when I use different vlan methods:
no vlan:
dev.hn.1.rxfilter: 9<DIRECT,BROADCAST>
dev.hn.1.hwassist: 17<CSUM_IP,CSUM_IP_UDP,CSUM_IP_TCP,CSUM_IP_TSO>
if_vlan:
dev.hn.1.rxfilter: 20<PROMISC>
dev.hn.1.hwassist: 17<CSUM_IP,CSUM_IP_UDP,CSUM_IP_TCP,CSUM_IP_TSO>
ng_vlan:
dev.hn.1.rxfilter: 9<DIRECT,BROADCAST>
dev.hn.1.hwassist: 0
All the other sysrc's either stay the same or seem to be counters.
I can provide you with scripts to setup vlans and jails with both if_vlan
and ng_vlan if that helps.
Any help understanding what these sysrc's do, or on how I could get ng_vlan
to work would be very appreciated.
Best,
Reshad
