I have been trying for a while now to set up my HTPC running Win 7 to properly be able to wake it remotely.  This would enable me to do cool things like wake it and check scheduled recordings or remotely access it via my mobile if need be.

PC is in the lounge connected by wire to the Orcon genius router. When the computer is hibernated (usual state when not in use, couldn't get sleep to work properly and still wake to record shows) I can trigger it to start up with the remote via a USB IR receiver.  I have also had success in getting the Xbox 360 (also wired to router) to start up the PC when I use it as an extender using media centre.  To me this would imply things are set up right to wake the PC remotely, but I thought perhaps I'm missing something since waking over the internet requires something extra.

I have set-up a dyndns.org account to use for remote access,  I have all the usual settings configured right in my NIC properties like Wake on magic packet and "Allow this device to wake the computer" and have the setting turned on in BIOS. I have the ports forwarded.

I thought for a while that my power supply didn't keep the on-board ethernet alive when hibernated since the indicator light goes out when the PC hibernates.  However, the 360 waking the PC would suggest that it does retain enough power when hibernated to be able to receive the signal.

I thought maybe it was a limitation of the Orcon genius unit?

Most routers will block it by default. There might be an 'enable' for it.

If not, you need to manually create a port forward to the broadcast address.

What are you using on the internet side to generate the wake-on-lan packet?

Wouldn't the router be responsible for sending the WOL packet if you have forwarded port 80 or whatever? I imagine the average router just forwards the traffic and assumes the server is always on... I would have another go at setting up sleep mode again. Alternatively... use a dialup modem just to wake the server, or keep it on a UPS in a dust-free space so that you can run it nonstop.

Have a look at this
http://www.ezlan.net/WOL.html

Up until reading that, i always thought WOL was a non-tcp/ip based system where a magic packet was sent to a computer outside of the TCP/IP stack and therefore wouldnt work outside the local network - but apparantly not. That link above should tell you more.

The forward to broadcast is needed since the PC will not be responding to arps to be able to receive the frame any other way.

I still found it problematic with forwarding an external port to the .255 of the lan. Ended up just sshing into the firewall machine and running a script I found a long time ago.

Now I have downsized the lan I have my one PC on all the time anyway so not needing to do it anymore.

Thanks for suggestions so far guys.

I will definitely read up some more on the weekend, especially that link, looks very informative.  Will reply if/when I make any progress.
