OK, this is solved now so thought I would post back to the list in case future users search the archives for the same problem and for anyone who is interested ;)
Thanks Tony, you answer was partially it. I hadn't correctly enabled WOL on the NIC card:
I don't know about your Dell, but on my HP ML110 servers, I had to add a line to ifcfg-eth0 to make ethtool tell the LAN port to enable the wake-on-lan function:
ETHTOOL_OPTS="wol g"
You will need to take the interface down and up after adding the line.
Cheers Tony
Also the other problem was I was using a dual Gigabit NIC, in particular I was using the 2nd port, but it turns out WOL only works on the first port! Just in case anyone finds them self's in a similar situation!
Many thanks, James ;)
