Wake-on-LAN with DIR-825
« on: October 07, 2009, 09:33:44 AM »
I have a DIR-825 router with Hardware Version B1 and firmware 2.01EU build 12 (May 22, 2009). I have a problem with Wake-on-LAN when trying to wake my computer with a magic packet.

If I try to wake the machine up instantly after putting it to sleep it works perfectly but after a short while the computer will not wake up any more. So it seems that I know how to send the correct packet, the correct ports shouls be open in my router and the network card and its driver are configured properly.

I know there has been a lots of discussion about this on other DIR models' discussion pages and I do know e.g. this thread: http://forums.dlink.com/index.php?topic=5934

My problem is that I cannot get even the proposed solution working. My router IP is 192.168.0.1, subnet mask is 255.255.255.128 and DHCP range is between 192.168.0.100 and 192.168.0.126. The machine I'm trying to wake up has the IP 192.168.0.100.

On the port forwarding tab, if I configure port 9 to be routed to 192.168.0.100 I can see with a sniffer application that the magic packet arrives onto my computer (and it wakes the computer from sleep if I try to send it quickly). If I change nothing else but the IP Address on the port forwarding tab into 192.168.0.127 which I believe is my broadcast address, the magic packet never arrives onto my computer even if it is up and running.

Could you please advice what should be done to get this working? I am quite sure I have followed the instructions correctly and have spent a lot of time with this issue. Is a working configuration even possible with DIR-825?

Jaska,
The broadcast address for your network 192.168.0.255. However you can not forward to the broadcast.

What I tried to do by changing my subnet mask was to have an effect on my broadcast address. I don't understand how the broadcast address would still be 192.168.0.255. So, is there any way to wake a sleeping machine from the Internet using a magic packet?

I don't think the broadcast address for my network was 192.168.0.255. Anyway, I changed my subnet mask back to 255.255.255.0 and had quite a lot of work to actually save the address 192.168.0.255 in my routers port forwarding settings (by saving the config file, modifying the configuration by hand and figuring out how the config file checksum behaves). It did NOT work. So, is the real answer that DIR-825 just cannot do this thing at all?
