I just installed a new NIC card with Wake-On-Lan, and having trouble
getting it working. It does work fine from within my home network, I've
used several utilites I've downloaded and I can successfully wake my
main pc up from my laptop at home. However, I cannot wake it remotely
from work. I'm again using several utilities, same MAC address of
course, the only difference is I'm using my routers IP address as seen
by the internet, instead of the internal IP address of the pc like I
would at home. Any suggestions?

To clarify, when I'm home, my internal IP address for the pc I want to
wake is 192.168.2.2, and by entering that and the MAC, I can wake it up
from my laptop. From work, I'm doing everything the same except for the
IP address, I'm changing it to 69.161.xxx.xxx (my home IP as seen by
the internet), but it won't wake. Shouldn't that work?

If your home computer is a 192 address then you are using some form of
NAT router - that means unless you set port forwarding, that you won't
actually be able to reach your PC.

You should not be "reaching" your PC from work anyway, work is where
you're paid for doing work, not for accessing your home computer.
 
Hello,

You might want to use port forwarding for WOL on your router. Also make sure that the WOL magic
packet is set to broadcast over the whole LAN (i.e. sent to 192.168.2.255). The WOL magic packet
will be sent to all the machines on the network but will only wke up the one that it has the MAC id
for.

Ok, I didn't realize it was a port issue, I didn't see any reference to
opening a port in what I've read so far. What port is used for WOL? So
if I open this forward this port on my router to the pc I want to wake,
that should do it? And this apparently only effects external requests,
because I can do it from an internal address (ie laptop) and it works,
yes?
 
Ok, disregard that last message. Based on what I just read, the normal
port used for WOL is port 9. So I should be forwarding port 9 to
192.168.2.255. Is that correct? I'll watch for your replies, and will
try it tonight from work. Thanks in advance!

Hmmm I tried to set this up, but it won't allow me. Here's what my
router says for my LAN:

IP address: 192.168.2.1
Subnet mask: 255.255.255.0

I tried to setup Port Forwarding for UDP port 9, WAN port range 9 to 9,
LAN IP address 192.168.2.255, to LAN port 9. And this is what it said:

"Invalid value for Port Forward LAN IP Address. 192.168.2.255 cannot be
the broadcast address."
 
Yeah, I'm not even getting to the client yet. Can't forward to
192.168.2.255 on my router. Any suggestions?
 
So if that's the case, what do I do to make WOL work? I'd imagine I
can't forward directly to the one IP address of the pc, since a pc that
isn't on has no IP.
