It is not sufficient to just ping the machine. You must send a specially formatted "magic" packet in order to trigger wakeup. Also, the machine needs to be sleeping - not completely powered off.
Some router firmwares (e.g. DD-WRT) support the feature from their web interface, or you can use a program like Apple Remote Desktop (http://www.apple.com/remotedesktop/) or Wake550 (http://www.tc.umn.edu/~olve0003/wake550.html).
That said, I am trying to get this working on my own 2007 MacPro, and not having any success (see http://discussions.apple.com/message.jspa?messageID=12481372). Any help would be appreciated!
