Sorry to cross link into different forums, however I created a guide for setting up VLANs on FreeNAS with 11.3.
Guide was made with 11.3RC2 and I hope things don’t change too much when 11.3 finally drops. I’m aware this topic of using VLANs with FreeNAS has created a little confusion, myself included. I figure I’d pass along a guide to help others as it took me a lot of trial an error particularly since I have a combination of jails, bhyve and iohyve VMs on my system. I don’t have any Warden jails so I can not speak to the validity of the guide if you’re still maintaining old Warden jails vs more modern iocage jails.
