I am setting up my old 2012 Mini to be a home server. I have a Time Capsule that I have used as a NAS and has served me well, but I decided I will just use the Mini for NAS purposes and the TC solely for Time Machine backups. Ideally I'd like the Mini to also act as a syncing service and VPN. I am looking at Seafile for the syncing service, but any thoughts on a good VPN for macOS? Any other software I should be looking at? Is it worth it to setup an "Open Directory" so each "user" (my spouse and I) can automount network shares when we connect on our various Mac and Windows machines to the network? Thanks for any input!
