You don't need gwakeonlan for the port to be triggered, or system power
on.

Double check:

$ sudo apt-get intall ethtool
(if you don't already have it installed)
$ sudo ethtoool ethx (x = 0,1,2 etc)

Check:
	Supports Wake-on:
	Wake-on:

$man ethtool:
<http://manpages.ubuntu.com/manpages/precise/man8/ethtool.8.html>
 wol p|u|m|b|a|g|s|d...
              Sets Wake-on-LAN options.  Not all devices  support  this.
  The argument  to  this  option  is a string of characters specifying
              which options to enable.

              p   Wake on PHY activity
              u   Wake on unicast messages
              m   Wake on multicast messages
              b   Wake on broadcast messages
              a   Wake on ARP
              g   Wake on MagicPacket™
              s   Enable SecureOn™ password for MagicPacket™
              d   Disable (wake on  nothing).   This  option
                  clears all previous options.

If 'Wake-on' is set to anything other than 'd':
$ sudo ethtool -s eth(x) d
will turn it off.

If 'Supports Wake-on' shows anything in addition to 'g' and 's' (i.e.,
pumba), then WOL can be triggered without a "MagicPacket™".

You might also want to check acpi wakeup:
/proc/acpi/wakeup

Anything in the logs?
