You have a PC at home that can be controlled via Remote Desktop Protocol (RDP)
or Virtual Network Computing (VNC). You want to use it from outside your LAN.
Start your HomeTunnel VPN and use an app (look for "remote desktop" in your app store) or PC Software (MSTSC.EXE,
RealVNC, TightVNC or equivalent) to control your PC from remote. If your PC is off, you can even power it on from
remote via Wake-On-LAN
