The configuration effort of this method is higher and more complex than in method A because you have to set up your router accordingly.
If you can answer the following questions with "Yes", this is the appropriate method:Is the target computer located in a network?Is the target computer connected to the internet using a network cable?Is there a second computer (PC, Mac, Linux) located in the same network?Does TeamViewer start automatically with the operating system on both computers?Is the second computer turned on 24/7 (the operating system and TeamViewer is running)?If yes to all the above, you can wake up the target computer in three easy steps:Configure the hardware of the target computerConfigure TeamViewer on the target computerWake up the target computerPlease refer to the TeamViewer Wake-on-LAN manual for a detailed description of how to set up Wake-on-LAN with TeamViewer.Wake up the target computer via its public addressChoose this method if the target computer can be reached via a public address. This is the case if you have either a fixed, static IP through your Internet provider or if your router has a public domain address with the help of a dynamic DNS provider. In these cases, you can configure TeamViewer in such a way that the target computer is woken through this address. This method requires considerably less configuration effort than the second method.
The second computer acts as a kind of “middleman” to forward the wake-up request to the target computer. a server) within the network of the target computer that is turned on permanently. In this case, you can use the second computer to wake up the target computer. Windows and Linux PCs, however, can be woken up from sleep and hibernation mode as well as being fully powered down, so long as the hardware supports this. How to use Wake on LANWake-on-LAN can be used through two different methods: Wake up a computer (hereafter called the target computer) via another computer within the same network. Wake up the target computer via its public address. Choose one of the methods depending on the circumstances.Wake up the target computer via another computer within the same networkChoose this method if there is a second computer (eg. Macs can only be woken up from sleep mode.
This means you can control an offline computer remotely by waking it up first before you establish a connection to it. You can initiate the wake-up request from another Windows or Mac computer, or even from an Android or iOS device running the TeamViewer Remote Control app. ?Note: It’s not possible to wake up a Mac computer that is fully powered down, as Apple doesn’t allow this. GeneralThis article applies to all TeamViewer users.You can turn on a sleeping or powered-off computer using TeamViewer’s Wake-on-LAN feature.

I have tried Wake-on-LAN Packet Sniffer 1.1 on Windows 7 and used the Wake-on-LAN Packet sender of the same vendor (Power Management Software). As I explained in my article about the free SolarWinds Wake-on-LAN tool, Magic Packets consist of six bytes of 255 (hex FF) followed by sixteen repetitions of the target computer’s MAC address. In the screenshot, you can see that the tool can even create pictures of these shy creatures. Hence, Wake-on-LAN Packet Sniffer also works on boards that don't support Wake-on-LAN.
These last two errors can't be ruled out with the Wake-on-LAN Packet Sniffer because you have to use the tool when the PC is already fully awake. Another cause of error can be the NIC, which is either not configured to accept Magic Packets or simply doesn't support Wake-on-LAN.
This only works if the routers in your organizations are configured to forward broadcasts containing Magic Packets. Problems often come up if you want to send Magic Packets across routers. Usually, Wake-on-LAN tools work reliably in LANs. What I mean is, if a PC doesn't wake up even though you have bombarded the machine with Wake-on-LAN Magic Packet frames, you can boot up the machine manually, launch the Wake-on-LAN Packet Sniffer, and see if the Magic Packets really arrive at the NIC of this PC.
