Ok, stupid question from a stupid person: if I have a phone connected to a local WiFi network, and I type in the URL of a subdomain which points make to that same network ie a hosted service on a home server, what route does the data take from the service back to my phone?
Pretty sure truenas scale can host everything you want so you might only want one server. Use Epyc for the pcie lanes, and a fractal design r7 XL and you could even escape needing a rack mount if you wanted. Use a pcie to m.2 adapter and you could easily host apps on them on a mirrored pool and use a special vdev to speed up the HDD storage pool
The role of the proxmox server would essentially be filled by apps and/or VM you could turn on or off as needed.
Have you got a recent copy of the configuration file?
Thanks!
