If you want to know for sure if the packet is getting to your router - then you would need to be able to sniff traffic on the wan port of your router? If your router does not support this - then you could always just plug a PC into your cable modem so it has a public IP, then capture with say wireshark - send the packet from outside and then see if gets there. Doing it from the public net can be hit or miss, as already mentioned its possible the port is blocked between where you at and your router. Ie I can vpn into my router, and then just use its builtin feature of wolĪnother option is to have some machine on your network you can remote to send out the packet on the local network. Sometimes if the router supports dhcp reservations it will know the mac of the computer and you forward to the computer name in the rules.īest bet to get wol working from the internet is to have a router that supports doing it. If your router will not allow for forwarding to the broadcast address, then you need to make sure it has the mac in its arp table. Are you sure this tool uses UDP 9? Other tools use for example 65535, or 2304

That magic packet has to be sent to the specific mac. When your machine is off, its not going to answer to arps. So if you local network is say 192.168.1.0/24 - the broadcast address would be 192.168.1.255 Normally for routers to allow WOL from outside you would forward to the broadcast IP of your local network, not all routers support this.

But if you machine has been off for any time at all, the routers arp table will no longer have the mac for that IP address. Where you run into trouble with trying to do WOL from across the net, is does your router know the mac of your machine? You can forward to an IP all day long.
