Can I still connect to my server if it is connected on public network (Client side is connected to different network).

Hi,

I learned about your product from the internet and am planning to buy it! But before that, I want to make sure my setup is streamable.

I wonder if I can connect to my server computer (a Mac mini), which is connected to a public network (e.g., a college network that needs authentication), from a client computer (a MacBook), which is in a different network. 

If so, how can I set it up?
