Hi Eugene you should be able to accomplish this by not using any “vlan_id” in
the nic config. Keep in mind that the GZ NIC should be in an untagged VLAN and
your switch should allow passing tagged frames. On some switches you may need
to change the ethertype or enable Q-in-Q. This varies by vendor.
If you’re going to be using this VM as a router you’ll need to enable ip and
dhcp spoofing to enable ip forwarding,NAT, and dhcp server responses. You do
not have to enable ip_spoofing on your external interface but you do on your
internal NIC’s. Now I’m not sure but to pass VLAN tags you’ll probably want
unrestricted traffic and potentially promisc access.
Also be sure that if you’re passing tags that you increase the size of your MTU
accordingly in the GZ and on the switch.
I haven’t tested tagging VLAN’s from within a guest myself but try this config
and let me know if it works. Also I would do this on two different GZ’s in 2
different guests in order to verify that the configuration is correct all the
way through the switch.
Snoop and Tcpdump are going to be your friends with this project.

Hi, I am fairly new still to Smartos and learning my way around it. I have been
in the process of migrating my environment from VMware ESXi to a Smartos host.
I have a Vyos virtual router that I would like to migrate from VMware to
Smartos. In VMware I know how to assign a trunk port to the Vyos virtual
machine and then assign various IPs in different VLANs for routing in the Vyos
router. I am not sure what the equivalent way of doing this is in SmartOs. I
know that you can add the vlan_id tag to the JSON file for the KVM machine but
given I want a trunk port assigned to the KVM machine (that will be running
Vyos), how do I go about doing this? Hopefully what I want to achieve makes
sense. Thanks, Eugene
