Re: WOL Through Cable Modem and Router?
To enable WOL remotely via the internet, through a router:
1. Set up your system so that the WOL feature is enabled and working properly. Before you try to wake the system through the router, first verify that you can do so through the LAN.
2. Configure the router to forward the port you want to use for WOL. If using DSL Reports WOL tool, that would be UDP 9. For Magic Packets the port is 2304. I have a WOL utility that allows me to specify any port, so I've chosen a random port that is not utilized by other applications. This was simply for security.
When your computer is off it doesn't have an IP address, even if it has been assigned a static IP, so you must forward to a multicast or broadcast IP such as xxx.xxx.xxx.255 - NOT the IP address of a specific computer. For example: 192.168.1.255, if that's the range you're using. Although this will be sent to every system on the LAN, only the one with the matching MAC address will respond.
3. Using a WOL utility, send the wake up request to the IP address of the router, specifying the appropriate port number, and including the MAC address of the system you want to wake.
4. Some WOL applications require you to enter a subnet mask as well - be sure to enter 255.255.255.255 so that your full broadcast IP address is obeyed.
This is the WOL client I use, and it works well: »www.depicus.com/wake-on-lan/wake···-gui.asp
If your router is assigned a dynamic IP address by the ISP you'll have to have some way of knowing what the new one is whenever it changes, but there are several other programs out there for this.
I also saw a suggestion on a another recent thread mentioning the use services such as www.dyns.net to map a domain name to your dynamic IP address, so you don't have to track it when it changes. I think that's a great idea if you use WOL frequently. |

|  Hi, I don't get it! sorry. You said I should specify an address range. for instance my ip is 12.242.200.58. should I put x's instead of IP address to specify a range? Could you please bring an example? I've also downloaded the little program... it asks me for a port. How can I find out what port I should use in there? My computer's wake on lan is enabled and I know what my mac address is. My card also supports wake on lan. Thank you. |

The example was for waking computers on a private IP address behind a router with NAT. Let's say you have the following setup:
A computer with an IP address 192.168.1.2, sitting behind a router
The router with a LAN IP address of 192.168.1.1 and a WAN IP address of 12.242.200.58 (that was provided by your ISP's DHCP server)
Then you would configure the router to forward a UDP port to a broadcast IP address for your IP range - i.e. 192.168.1.255. Using the WOL utility I recommended, you can choose any port you like - so let's say you pick UDP port 12375.
Under the scenario you would configure the WOL utility as it appears in the image provided. |

IF the Answer is Yes, kann I do it with a "MC 7004 VBR DSL-Router"?
Thanks in advance for your help |

| I tried also to do it, and did what is explained in this topic, but it doesn't work for me. I have a 3com 812 router, private network 172.26.0.x with mask 255.255.255.240, so broadcast address is 172.26.0.15
I have put NAT to route UDP port 7 to UDP port 7 of the broadcast address.
It doesn't work. Any idea?

You can`t use x.x.x.255 (only to 254)by SMC 7004 VBR.

| Me too, I don't speak english fluently !
I have a server (windows 2000 server) and I tried to forward port UDP to the broadcast IP address, but it doesn't work. If I send magic packet from the server, the pc on lan wakes up ! but if I send it over internet, it doesn't work.
I'm using RRAS from windows 2000 server !
The ip address of the public interface is assigned by ISP DHCP server.
The ip address of the private interface is 192.168.0.1
So I tried to forwarding the following port
UDP 7 to 192.168.0.255
but the pc doesn't wake up ! I tested if the server received the magic packet, and it does ! but it seems that the PC doesn't receive the magic packet forwarded
Any idea ? |

| I have A DSL/CABLE ROUTER(I use it for DSL) and you must configure your router(As someone stated above). And if you have an onboard NIC you might want to make sure its powered when the system is powered down(On my comp u can't tell by look at the LEDS if its powered or not).
Heres how my configuration looked when i got it to work.

| I've got a little bit of a weird set up from my ISP. When I trace my public IP from my comp, it looks like this:
1 1 ms 1 ms 1 ms 192.168.0.1 (router's IP)
2 1 ms 1 ms 1 ms 172.19.24.150 (don't know what this is)
3 29 ms 13 ms 13 ms arizona.netbeam.net [216.58.148.244](public IP)
How would I go about setting this up?
Also, on my WAN IP is something weird like 10.1.1.2
Hope I provided enough info to get some help |
