I need to configure WOL over the internet. 

For that i'm: 1 using the DDNS tp-link provided; 2 i did forward a port through "Ip Reservation"

From what i have read i need, now, to configure an "ARP" list. So the router can sand the magic packed when the client is turned off. (please correct me if i'm wrong"

That's the question. Where/how do i do it on the app configurations? 

Is there a guide to how to configure a WOL over the internet on the Deco x20 app?
