I was trying to do some research but couldn't find much. I am trying to advise a friend of mine who has her own business and needs her files that her employees work on updated and sent back to her home (wireless network). I had advised a NAS so when the employees are at her home business they can work and update and send the file to the NAS there. But what about when there on the road? Does the NAS support anything so that they can login remotely into the NAS and send the updated files like that?
