In this case replace $Broadcast address by the destination public IP, and open/forward the specified $PortNumber (UDP) on destination.

The above one-line bash command should work too for wake on LAN via internet.The specific port number seems not to be important on WOL. NetCat's OpenBSD version has a bug as for today (Juy 2015) on broadcast data sending ( -b), so you will have to replace it by NetCat Traditional version (netcat-traditional package on apt-get installers).CygWin's NetCat version doesn't need for -b parameter.

Tested working on Ubuntu, Kali and even CygWin (Windows 7 SP 1 64 bits ). SoCat can be used instead (syntax will differ, of course).

The forged wake on LAN package is sent to the network stack piping it to NetCat.

and so on) prior to sending the string to the network stack.

The sed command is used here to remove colons ( :) from the MAC and to add the \x hex specificator (so that 11 becomes \x11, 22 becomes \x22.The WOL magic packet is composed of ffffffffffff (12 times f) followed by 16 times the destination MAC without colons ( :).The command line would be: echo -e $(echo $(printf 'f%.0s' ) | sed -e 's/./\\x&/g') | nc -w1 -u -b $Broadcast $PortNumber Bash supporting brace expansion (I think it is v3.5.1 and above).The received WOL Packet contains MAC Address 00E04C3103AC and empty password.The minimum requirements I can think off: The example below shows the packet sent from IP 192.168.1.4 to subnet-directed broadcast address 192.168.1.255 and destination port 7. Start your Wake-On-Lan tool which be used to send out magic packets. Start Wake-on-LAN Packet sniffer on the target (tested) machine.Last two ways requires configuration of the routers for each subnet. If the router or switch still has cached what port that computer is attached to, packet gets access to the machine. Unicast: the Packet sent directly to the machine IP address.

The router or switch will forward the packet to all the machines on the subnet.

Subnet-directed broadcast: the Packet sent to the target machine subnet.

Limited broadcast: the Magic Packet sent to the limited broadcast address (255.255.255.255) it is received by all machines on the same subnet but not forwarded to machines on other subnets.

There are three different ways to send Wake-on-LAN packets: This packet should contain a synchronization stream of 6 bytes of FFh and 16 times the repetition of the MAC address. The Magic Packet is a UDP broadcast message, that contains the Media Access Control (MAC) address of the network card of the target computer. Wake-on-LAN (WOL) technology is used for remote waking up machines from sleep state through special network packets (Magic Packet). Program will display all incoming "Magic Packets". It allows to check whether the target machine receive the packet or not. Wake-on-LAN Packet sniffer is designed to troubleshoot and setup Wake-on-LAN in the Network.
