I tried the support number but they didn’t know what I was asking and said someone would call back, still waiting, not holding breath.
Most routers have a broadcast IP address. This is an address that when you send a message to it, the message is forwarded to all connected devices. Its a standard network protocol. Typically it might be used for using the WOL feature over WAN network. On the BT router, i think it should be 192.168.1.255, but it doesn’t seem to work.
Err, no. That's the IP address of the hub. 192.168.1.255 is the broadcast address of the subnet.
Should be 192.168.1.255 right? Ill try it again when BT finally get my broadband working.
What are you actually trying to do, you will find that most devices don't respond when pinging a broadcast address.
I want to wake up a sleeping computer. It works fine over the lan, but i would really like to be able to do it from anywhere in the world. For example I will be in korea soon and may need to access that computer.
First of all I'm not sure its possible to forward ports to a broadcast address but even if it is it would be preferable to give your PC a static IP address outside of the DHCP range of the hub on the PC itself and just forward the WOL magic packets to that address alone. You only need to broadcast if you want to send to more than one device or the device IP is dynamic.
