[SOLVED] Wake on LAN doesn't work over WAN

Hey!

I'm trying to setup WOL on my PC. It works fine through LAN from my notebook using the broadcast address.
E.g.:

Code:

# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:01:02:03:04:05  
          inet addr:192.168.1.101  Bcast:192.168.1.255  Mask:255.255.255.0

Code:

wakeonlan -i 192.168.1.255 00:01:02:03:04:05

The problem is if i'm trying this over WAN using my global IP address, it doesn't work.
Portforwarded to the local IP (192.168.1.101), didn't work.
I thought maybe i should portforward to the broadcast address, but the router doesn't allow forward to x.x.x.255, only x.x.x.254.
What should i do here?

I'd appreciate any advice!
Thanks in advance!

EDIT: Assigned the local IP to the PC's MAC address and portforwarded to the local IP, now it works most of the time. It's pretty unreliable tho, sometimes it just doesn't wake up, i have to send several packages.

If I may suggest something you can try (I doesn't work for me neither, but it improved the number of tries)
is to set in your computer's BIOS the Standby mode to S1 (the link has a nice explanation about different modes), but it's not 100% sure (as usually with computers there is nothing 100% )

good luck

Generally private IP ranges are on the web but the actual route to any host is almost impossible to predict. I am surprised you got it to work once.

I think this is a good explanation:

That example is a public ip.
