> Hi Rod, > Can you share a command line for that? Its not just a single command, but you want these in /etc/rc.conf of the GUEST: network_interfaces="lo0" cloned_interfaces="vlan48" ifconfig_lo0=" inet 127.0.0.1 netmask 0xff000000" ifconfig_vtnet0=" up" ifconfig_vlan48=" inet 192.168.48.38 netmask 0xffffff00 vlan 48 vlandev vtnet0" That may be your issue... is your vtnet0 "up" in the guest. It would help a whole lot to share more of the info about your system, from commands, not from "vm-bhyve" settings. Like ifconfig -a on the host and the guest would be a starting point. > I also tried presenting an access port from my switch on a specific VLAN - not trimmed. Trimmed? You mean you set the switch port to untagged mode, and had the switch tag/untag the packets to a specific vlan. Be sure you also set the default incoming tag at the switch if you did this, some switches do not follow the vlan setting. > Would I still have to tag the interface on the guest in that scenario? No. If I understand what I think you meant by trimmed. > Regards, > > > Paul Esson | Redstor Limited > t +44 (0)118 951 5235 > m +44 (0)776 690 6514 > e paul.esson@redstor.com > > ________________________________ > From: Rodney W.

I have two NICs and have configured the first (igb0) on a management network and want to use the second (igb1) for VMs. However, I can't get any VM to communicate through the virtual switch if I have igb1 added to it. If I take the NIC out of the switch and configure an ipv4 address on it I can reach other hosts on the relevant subnet so I believe the poet set-up is valid. If I replace igb1 in the switch with igb0, I can then configure VMs on my management network and they have network connectivity.
