Lanz Bullshit Forum » Wake On Lan doesn't work

HI,

I have t his problem in two computers with Linux Mint 17.3 x64 KDE.I have configured the router for redirect the port for WOL to my computer and the computer have a static ip assigned by router.
I have the 2 computers in differents locations (not are in the same lan).I sleep the computer, and in the first 10 or 15 minutes I can wake up by WOL without any problem, after this 10 or 15 min. I view t hat, I need made 2 clicks (in my smartphone for example) for wake up, but after about 30 minutes I can't wake up the computer, any of my 2 computers.This 2 computers, with win7 I can wake up without any problem, I sleep the computer and I can wake up after 24/48/72 hours....since I sleep the machine.I search about this but I don't view any and its a problem for me because, win7 I have only for test this issue and I need sleep the computer at the night.If I install the soft Wake Up, and program this soft for wake up after a 8 hours since sleep computer, wake up fine, but only with the soft installed in the computer and programed for wake up at one hour. I can't wake up remote.

Please help.

I did not find the right solution from the internet.
