I'm trying to do a WOL for my Xenserver in my lab environment. However I am not able to do it. I have enable the BIOS settings of the physical server, and from what I can see, even when the server is turned off, the LAN led lights is on.

Also I have enabled port forwarding in the router like this setting:

Name: Wake-on-Lan IP address: Port: 9 Protocol: UDP

And I tried to do arp add 001E90E36581 9 and did a ping to that IP but I'm not getting any response.

What program do you use for WOL? The IP address is irrelevant, you need to send a broadcast packet at link level. –  ott-- Jul 24 '12 at 20:26
@ott-- How can I do that? –  xybrek Jul 25 '12 at 1:32
For what system do you need that? You can download tools for windows from the net, and a simple perl script for Unix/Linux as well. –  ott-- Jul 25 '12 at 14:38

It may be that you haven't enabled WOL in windows. Start-> right click (my)computer -> properties -> device manager. Find your network card. Right click the sucker, then click properties, power management. Make sure that the box is checked "allow this device to wake the computer. Now go to the advanced tab. Scroll down to "Shutdown Wake-on-lan" and make sure it's enabled. Also make sure "wake on magic packet" and "wake on pattern match" are enabled.

EDIT: In case you haven't enabled WOL in bios, here's how to do it. Restart (or boot) your PC. Press the DEL key or whatever key you're told to press to enter BIOS. Once you're in BIOS, look for Power Management and then WOL settings (not all BIOS are equal in appearance, so WOL settings might be named something different). If you find it, enable it then save and exit. If you're not sure what your BIOS labels WOL, go to your BIOS website, lurk around or submit a question asking where to find the WOL settings.

WOL must be enabled in BIOS. –  ott-- Jul 24 '12 at 20:24
I was under the impression that xybrek enabled WOL in bios? –  AVandelay05 Jul 24 '12 at 20:26

You cannot use wake on lan remotely. You have to be on the same network as it is a special layer2 packet. Some home routers allow to send wol packet from their web UI.
