I was just testing out Pulseway for my organisation. Wake-On-LAN works fine when on same network through pulseway app. I want this feature over WAN. I have already configured port forwarding in my router. But it gives error - wake-up command failed. Since this feature works on local network, I can simply assume that my network adapter and BIOS settings are configured correct. What might be the problem over internet? (Also: 3rd party WOL apps on Android do not even work on same WIFI. This can relate to some problem). Please assist me.
