Got this app to be able to wake my Windows 8 PC via the Internet. I have a Microtik Router and didnt have to do much to let the packet in.
Note windows 8 requires:
1- Open the Power Options in Control Panel
2- Select “Choose what the power buttons do”
3- Uncheck “Turn on fast startup (recommended)"
4- Select "Save Settings"
