I'm setting up a Mac Mini to work as a server in our office (nothing fancy, mainly a file server). It'll be run headless so I've been setting it up on my home network ready using the in built Share Screen function. Once it's in the office, I'll want to be able to connect to it externally from home to change settings, do maintenance etc without having to go into the office. I know I can use the vpn functionality of our office routers (Orbi Pros) to connect if I have to but that redirects all of my traffic which is a bit overkill (but secure). I'd rather not have to use third party software but if that's the best solution then I can do that. Any suggestions?
