I don't really want to tamper with port forwarding, SSH-tunneling and VNC instead for this project, especially as there is the possibility that there may be more than one computer in the refugee shelter in the future, which just adds to the complexity I'd have to deal with in my spare time, when I'd really like to do something more worthwhile, exactly the reason why I'd hoped that Teamviewer would work. But now it's either SSH-tunneling or getting somebody on the phone and making them understand that I need them to log in to the computer before I can access it.
