    Wake on Lan/Wan (WOL) Support

    I am trying to get Wake-On-Lan to work. It works fine when I send the magic packets from a computer on the LAN (using Wake on Lan), but fails when I try from internet like from http://www.depicus.com/wake-on-lan/woli.aspx. I have forwarded port 8000 for this purpose. Some forums seem to suggest that the Magic pakets be "Broadcast" to all local addresses. This does not seem possible (one can not enter "255") as last values of port forwarding address. Do you have any ideas?

    WOL and static dhcp

    Wake On Lan should work:

    1. Use static-dhcp and forward the specific port to this ip-adress, then broadcasting is not needed.

    2. Enable WOL in the BIOS of the specific pc.

    Still no WOL

    Yes, I have static DHCP setup and am using port forwarding (as opposed to port triggering) to forward ports 7999 to 8001 to that IP Address. The Bios is set correctly since I can wake the computer up from the LAN.
    Still WOL does not work when I try to use it remotely, as opposed to from a PC on the LAN.
    More ideas? Thanks.

    Still no WOL (PS)

    According to Depicus web site:
    "If you wish to use Wake On Lan over the internet you will need to set up your destination firewall/router to allow "Subnet Directed Broadcasts". Most routers and firewalls disable this option by default."

    Does this help?

    After your message I tested this on a router, and couldn't receive a WOL-packet too.

    The broadcast is not possible, iptables does not support broadcasting at .255
    I think this needs further testing.

    Did some more testing, and I have found the solution:

    1. Assign a static ip number
    1. Forward port 2000 for UDP to that ip number.
    2. Use the Wolgui with mask and port 2000
