I am currently working remotely due to the pandemic. I am one of very rare Mac user at my university. In Poland Macs are not popular, and our net administrator and our tech support have no or limited knowledge on macOS. I use desktop MacMini (at work) and MacBook Air (at home) both logged in with the same AppleID, running on Big Sur. I have installed Apple's Remote Desktop (v.3.9.4.) on my MacBook Air and want to connect remotely and work on my MacMini at work (screen sharing). I already contacted Apple's Tech Support and learned that to access remotely from different network router at my university's network has to have set a port forwarding (ports 3283, 5900). Can anyone provide me more details on that? I got feeling that I need a ready solution when I contact my net administrator with that to overcome unwillingness to tackle new problems.
Best regards, Marcin
