hi, more of a software question this but might need some router config too maybe?

any way here goes
im looking for some software, or just simply a way to use wake on lan over the internet.

i use a netgear DG834G router and i can get wake on lan fully operational from within the network (internal lan) using the amd magic packet software (intel chips let me just point out lol) what i want is to wake up over the internet.

so far all my efforts have been in vain, i have visited several websites which claim to offer this from their site and have had no luck.

i have ports open to forward to the pc but no luck. there is also a piece of software called nsnetwork tools xp i think which claims to be able to wake on wan but i cant get hold of it.

does anyone have any resolutions?

many thanks to all people who can help.

Hi. I have this exact same problem. It really comes down to whether your router supports this. I'll try to explain.

Wake on Lan packets aren't sent to a particular machine - they are sent to the whole network along with the MAC address of the machine to wake up (so every device on the network receives the data and only the device with the MAC address listed in the packet wakes up).

basically, when your machine is off (or asleep) your IP address no longer exists (since it's assigned by the OS). This is why Wake on Lan packets are sent to MAC addresses rather than IP addresses hence the broadcast to the entire network rather than a single machine.

I couldn't get this working with my router, but you may have better luck. Try opening the port up to your x.x.x.255 IP

(So for example if all the machines on your network are 192.168.1.1, 192.168.1.2, 192.168.1.3 and so on, then forward the ports on your router to 192.168.1.255)

This is because 192.168.1.255 is a special Ip which broadcasts to the whole network. Most routers won't let you add a rule in though allowing traffic in from the internet out to x.x.x.255 which is a shame.
 
u r a genius, i know u have to do that with the magic packet software i use but i never thought to set the router up with xxx.xxx.xxx.255.

ill try it later 2night and post bk results.

Hope it works
 
Nope it wouldn't let me set the inbound route to .255

anyone suggest any new routers?
i do like netgear tho.

or another way around this?

This was where I got stuck - my router would only let me specify a number between 1 and 254, yet 255 is the one you need to allow through. There are routers which support wake on wan, but I couldn't justify buying one.
 
Any examples of these routers on OcUK? (Netgear Preferably)

I am tempted to purchase one with higher speeds (mine is only 54mbps)

Well, I never got this working with my SMC router, and your thread has prompted me to have another shot at it :p (I hate quitting).

Anyway, I found this on another forum which looks very promising, i'll give it a try myself later, but apparently it has worked on netgear routers.

Since most Netgear routers won't allow you to forward to the subnet's broadcast address when it ends in 255....what you need to do is change the subnet of the router so it changes the broadcast address.

What you need to do is change the IP Subnet Mask on the router from 255.255.255.0 to 255.255.255.128.

Now when you create a Wake-on-Lan port forwarding rule, use 192.168.0.127 as the IP address. This will cause the WOL packet to be broad-casted to the subnet and this should cause your computer to boot up.

hello again
i tried it along with some internet based packet senders (http://www.depicus.com/wake-on-lan/woli.aspx) and a few other i found
but still no joy. did a search for subnet calculators tho and xxx.128 limits ip locations to xxx.126 and xxx.127 IS the broadcast address, so the theory seems correct, so its proberbly the packet senders not interacting properly
any suggested software?

What information did you put in?

As I understand it, for the one at depicus to work, you enter in the following;

Mac Address of computer (pretty self explanatory)
IP address (this will be your broadband external IP, for example 80.81.82.83)
Port - this is what you forwarded through your router (usually 7 or 9) to IP x.x.x.127
Subnet Mask (this is your broadband subnet mask, so if you have one IP address (which nearly everyone has), then you'd enter in 255.255.255.255

However, if like me (or most companies) you have a block of IP's (have 5 IP's - am using a no-nat setup), then you'd enter in a different subnet.
