A iPhone - iPod touch application that sends a WOL packet to a specific computer via the internet or LAN

Features

• Add as many computers as you want
• Works via the Internet
• LAN Broadcast
  

• Name: Can be anything you want here.
  
  
• MAC: Windows: Go to START, RUN, CMD, and type IPCONFIG /ALL. Find the PHYSICAL ADDRESS
            for the ethernet adapter.
           
            Mac OS X: System Preferences -> Network -> Ethernet -> Configure ->Ethernet -> Ethernet ID
           
            Enter this address in the format xx:xx:xx:xx:xx:xx
  
  
• Host: Enter the IP address assigned to your computer by your ISP or a DNS name if you have one set up.
  To see your WAN IP address, go to http://checkip.dyndns.org. If you have a dynamic IP and your router supports dyndns.org then create an accout by Clicking here
  
  
• Port: Usually you use port 7. You'll have to login to your router and forward the incoming requests for port 7 (UDP) to the IP address of the computer you want to turn on.
  
  
• LAN Broadcast: If your phone is connected to the same network the computer is on, turn LAN Broadcast ON. If you are using Edge on your phone or are connected to a different network, turn this setting OFF.
  
  

In order for this to work via the internet your router needs to be able to foward the magic packet from a port (e.g. 7 UDP) to the LAN IP of the computer you want to wake up.

Also it only works using an ethernet cable, it will NOT work through a wireless card on the computer
you want to wake up!
