As per normal routing standards, the UTM device will not forward broadcasts, which WOL packets are.
Are you using WOL on the UTM device..or some other host ?
On all but the lower end devices we have utility etherwake on the units.
from the command line
If you did this on the remote UTM device, all should work.
What I am trying to do is turn on a computer that is off on the other side of the VPN. The subnets are different on each side of the VPN.
Is it possible to send an actual WOL magic packet to the specific computer that needs to be turned on instead of a broadcast?
I will look into the etherwake command.
No...only the broadcast method is used to Wake on Lan
