Re: Was [OT] Help with power usage calculation, Now: Wake on lan problem

["Paul Robinson" <ukcueman@xxxxxxxxxxx>]

Don't know much about WOL, but since the original request is a broadcast,
maybe you need
to get the firewall to forward the packet to your local broadcast address
rather than
directing it to one machine.

The page you referenced tells you how to calculate your local broadcast
address.
