Setup Magic Packet Server

Download & install prebuild version for your platform. After that the server will start automatically and run as demon (for Unix) or as Service (for Windows). You don't need to start it manually.

Then add into MPS Address field your address like in screenshot.

For example, your computer have IP-address 192.168.1.5, then URL for you will be:
http://192.168.1.5:5154

The program can work over the Internet to do this, open 5154 port on your router and add a static DHCP rule. You can use this article as an example, but use 5154 instead of port 9. Once configured use your external Internet IP-address instead of your internal one.

For example, your internet IP-address 93.191.63.4 or domain name example.com, then URL for you will be:
http://93.191.63.4:5154 or http://example.com:5154

If everything is configured correctly and your computer is turned on, the green diode on the main screen should be lit. Try, for example, restarting your computer to make sure everything works.
