My wife does "work at home" right now, and to access her office computer she had to use our state's particular VPN network to access the office computer, and the office computer had to be set for WOL which is Wake On Lan, and the VPN server at the office needed a special access allowed for even that to happen. If your office has IT staff, then consult them about how you can do it. I upgraded her computer from W7 to W10 which was required, installed the "work at home" program required, but changes also had to be made at her work place by the IT there to allow it to complete the access.
Looking for advice/ steps to set up a network between my home computer and my office computer.
