Thanks Robin, I really appreciate the help. I think I'm alomost there,
but I'm a little confused about one thing.

Firstly, I am almost positive that the ethernet interface supports WOL
and I know the mobo does because I have read the specs and turned the
feature on in the bios.

The option to allow the network adapter to power on the computer has been
checked and there are WOL settings (currently set to 'wake on Magic
Packet'.

This leads me to believe that the port forwarding is my problem. This is
where I'm a little confused.

When I go to the 'Forwarding' tab in my linksys router settings, it seems
that I only have the option of forwarding to an IP. They even go as far
as to fill in the first 3 sections of the IP address for me
(unchangable). So, when I tell it to forward port 9, the only
information that it seems I can fill in is the .2. That is to say, the
168.192.1.__ is already there and I just fill in the blank with the
machine that I want to forward to.

If it is not to complex and you are familiar with the settings of a
Linksys router, I would greatly appreciate it if you could explain how I
forward to a subnet. Is this something that I can just do with the WOL
GUI that I am using, or does it definately have to be an adjustment made
to the router settings?

I'm working remotely right now, so my troubleshooting methods are
limited, but I plan to put the machine in the DMZ to see if that at least
gets me around the problem temporarily; until I figure out how to
accomplish what you have suggested.

Best regards,

Andrew
