Is it possible to send a Wake on LAN packet over the internet to wake up a remote desktop computer?

Is it possible to send a Wake on LAN packet over the internet to wake up a remote desktop computer that is connected directly to the internet by a Comcast cable modem? No firewalls, switches or other such devices are being used.

I like to keep my home desktop computer in sleep mode while I am not using it.

I would like to be able to send a Wake on LAN packet directly over the internet to wake up this computer whenever I need to access it remotely.

Is it possible to do this? If so, what specific programs or Wake on LAN utilities will allow me to do this?

Solarwinds has a free Wake-On-LAN utility you can try.

Also check out Wake-On-LAN Online (WOL).

Your cable modem probably has NAT (Network Address Translation), so your PC may not be directly accessible from the Internet without forwarding ports.

@DanCh99, LogMeIn wouldn't work in this case.
LogMeIn requires at least one other LogMeIn host on the same target LAN is online and available.

poweronmypc.com is free and does  it without installing anything on the workstations. logmein has to be installed on every workstation .

PowerOnMyPc.com also requires a "server" or "device" to be on the target network.

"The server version of the Power on My PC Wake On LAN product is a software application that needs to be installed in your network on a computer workstation or server that is always on."

@Knowledgeable, does the PC want to wake up have a public IP address?

it requires that the bios and network card support Wake on Lan.  http://windows7-issues.blogspot.com/2011/03/wake-on-lan-wol-for-windows-7-made-easy.html has a good summary of what to do and how to do it

true but that is only installed on 1 machine on the network, a server or any machine on the LAN that is always on anyway.

Any machine you want to WOL requires the BIOS and/or LAN card to support, so that is a requirement you will have to meet regardless.

Teamviewer will also do the job. As for the Wake on Lan it is very easy to do. Most new machine support WOL for power savings.  Thats why you are seeing large companies buying into the commercial products
