#Mac wake on lan internet mac#
Unless your router knows what MAC that IP address is on, its not going to forward anything normally. The table that points a IP to the mac address. "Could you be a bit more specific regarding the arp table?" It also asks to provide the MAC and the port number, quite simple and straight forward really so I don't think the problem is at that end. I enter a local IP for local activation and a remote IP for remote activation.

I should point out that the tool I have allows me to configure two options for each computer I set up on it. Many thanks for your help by the way for the second time this week :) I would consider buying a new router but with FTTC (VDSL) coming to my area soon I fear it would be a waste in the wake of potential new equipment requirements. I did have a netgear DG834PN which decided to die on me. I have a Sagem 2504 as supplied by my ISP in the UK (Sky). If I am connected to someone elses wireless or the 3G network, it won't. It's strange because if I use my internet IP and am connected to my wireless network it will work. You say your sending from your phone - is this phone on your wireless network? If so the packet would be broadcasted on your worked and would explain why its working.

Are you forwarding other traffic that works? Keep in mind sending packets to some IP from inside your network that you think are being forwarded back is not a valid test, especially with something like magic packets what would be broadcasted on your local network. What specific router do you have? Also what modem? lots of times users have issues with forwarding its because they are behind a double nat. If gets there - then there is nothing between where your sending from and your routers wan port.Īnother option would be to put a hub between your router and modem and plug your sniffer into the hub and watch the packets that way.

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.
