I have read the article in the web page but I am not certain if I understood correctly. The following is my understanding of what is said under the heading of "Wake On LAN over the Internet":

The process advances in the steps as follows:

1. Send from the internet, "WOL packet" with a port # specified, to the router.
2. The packet is port-forwarded to an internal broadcast address.
3. Then, broadcast packets are sent out into the LAN.
4. The target PC is turned on.

In order for this to work, the router is capable of recognizing the "WOL packet".

Is my understanding as above correct?

Churin,

yes, that's one possible way, but to my knowledge this doesn't
work with most routers. It seems that the router has to help a
little bit, and most routers don't do that. You have to try and
see if yours does it.

The other, more promising method is to find out whether your
router supports some method. My router, for example, does it via
a telnet command, as you have already read in
http://winhlp.com/WxWOL.htm .


I guess that I should ask router venders weather they have routers which allow WOL control via the Internet.
Thank you for your help.
