Hey Dude,
I had this issue after changing the network from 3 flat vlans to inter-vlan routing. Typically WOL uses udp protocol 7. You have to state which IP address the WOL broadcast packets will propagate from, for me the 2 servers in red in my server-farm send this out at 7:45 every morning. Please see my active config below.
Also remember that your server team will need to test the script, so once you added this config if they try & bounce the problem back to you then its not your problem.
