WOL Fails from outside the LAN
Posted on 2012-04-12
I use WOL to wake up my home computers so I can remote into them from work.
WOL fails to wake up the machines when I send the magic from work
I have port forwarding set correctly & the magic packet sent from the remote (work) network IS received correctly on the home PC(s). (WOL Magic Packet sender has a receive mode where I can check this)
WOL is 100% effective on all my home PCs when the packet is deployed from the local network.
The only way I have of waking up a given home machine is to leave (any) 1 on and use that to do the waking up of the others.
I would like to be able to suspend them all because I hate wasting electricity and wearing out my fans etc.
I haven't specifically opened the port/s I am using for the UDP magic Packet in the (windows) firewalls on the PCs I am trying to wake.
Why can it wake from any PC on the local network but not from work even though the packet is received on the home PCwhen I send it from work (once its awake I can test).
Can anyone say how to sort this out?
PS the home PCs are not on a domain but OS include
WHS (spx -up to date)
Vista (spx -up to date)
