I have a rack with several different generations of Poweredge 1950 and some R610s.  I want to remotely (WOI) start, stop and operate the systems in the rack.  The systems do not have the DRAC boards installed. I have setup WOL for all systems and can start and stop them all on the LAN just fine.  If I can remotely start a single p1950 system, then I can easily start and stop all systems using that single system. But I can not get the single p1950 system to start remotely.  I have set Port Forwarding on my DSL modem/router to forward UDP 9 to the system and it sees the magic packet just fine... but it will not power on. I am unfamiliar with the DRAC boards and the various remote management tools but from the reading I've done... it seems possible to be able to power on and off the machine from the Internet.  Can someone please explain what I would need to be able to remotely power on the system? Can I do it without a DRAC board installed? What software is needed to send connect with the system and send the signal to power on? Thanks! 
WOI for Poweredge 1950
