Alright,
Wake on LAN always works.
Wake on WAN works via dslreports after very short period of time after sleep.
Wake on WAN DOES NOT work after long period (~5+ minutes after sleep)
It would appear I have the correct settings set given the scenario. I've done the obvious.. Set BIOS and Windows settings correctly to my knowledge. I'm lost as to why I can't get it to wake up on wan after while. Any help... Very much appeciated. Thanks.
