hey. i have wake on lan on my xpenology box working.
you just need to enable in the bios: poweron by pci/pcie or both if you have
then also enable it in DSM
i have an android Phone and use the app Wake On Lan https://play.google.com/store/apps/details?id=co.uk.mrwebb.wakeonlan&hl=nl
in the app set the mac adress to the one dsm is saying not the one your network card has
for the hostname/IP/Broadcastadress you will need to fill in your external ip. you can look that up on this website:http://www.whatsmyip.org/
for the port just use any port like 5000
