Thanks for your comment. This plainly tells me, for now, find another solution, unless you suddenly enabled it all at once in a few days, without too much bugs.
This brings up another question I've had though, which I think is appropriate here. Upgrading. I know how to upgrade, I think. But I never found a clear statement of whether or not, beyond a simple one time, upgrade before, whether the device, I believe antsle one if I remember, but not sure, comes with free upgrades when I don't add a paid plan to it. I have to live with the free plan for now, but just wondering if it takes a paid plan for it to work or not, or the purchase of a new device. I bet I could find what release I'm running, if you need it to do that. Just wondering, because such features would only be in the upgrade, I think. That's OK, if it's out of my reach, but I don't want simply my lack of knowing I can do it, to stand in my way. I only want it when new features come up, if I do it, anyway. Like I said though, can't upgrade my plans now though.
Lastly, I know the protocols to share, either smb or ftp or both would meet my needs. However, what I don't know is if Windows or desktop/server Linux would be the best, or if proxmox at the very least, might run within those specs. And if proxmox can be setup to use those protocols in a web GUI way. Truenas, if it would run, would've been perfect for that machine. I want most features to share the drive, but want to run home assistant also. I don't want to run it unvirtualized, because of wasted resources. Virtualbox would work, since your guy's won't, but I don't know what OS is best to run it on for now.
Since yours won't work, and unvirutalized wastes space, i am down to proxmox (which I've never tried to date either), I don't know if they have a free plan, or down to Linux or Windows. First to narrow down, is can proxmox do it then, on those specs. Will it work and do they have the smb and ftp sharing, or do I need the other choices.
