Is it better to put OpenVPN (for PIA) on my OPNsense router, as an LXC on Proxmox, or the (soon to be deprecated) feature in my TrueNAS Scale VM?

I was going to use the built-in OpenVPN in TrueNAS until I found out it's going to be deprecated.

I only really need it for the qbitorrent/transmission and prowlarr/jackett (haven't decided yet) apps in TrueNAS, so I don't know what the next best option is.

I have found plenty of documentation on how to use the integrated OpenVPN feature of TrueNAS, but since the announcement of it's deprecation and future elimination is only ~2 months old, I haven't found any new documentation yet on alternate methods.

I see stuff about tailscale but that doesn't seem to be what I'm trying to do.

Thanks.
