Wake-on-LAN doesn't work from outside LAN

There was an error rendering this rich post.

Hi, I have been trying to set up wake on LAN but I can't get it working remotely from outside my network.

I have confirmed that my laptop will wake up when in sleep mode over my home network.

I have opened port 9 on my router and set up my public IP address in TeamViewer. I have also mapped my MAC address to my IP address in my router settings to ensure that I always get the same IP from the router.

I just cannot get WOL to work over the internet, it seems like TeamViewer is not listening on port 9 as when I check using a port checker it shows as closed. I have confirmed that it shows as open when a program is listening on this port (I tested with a bittorrent client and set 9 as the port).

Any help would be much appreciated,

Thank you.

HI @dfitz1000

Welcome to our community and congratulations on your first post.😃

From what I' m reading in your post, you are dealing with two different issues, one the firewall ports that TeamViewer needs to connect correctly and the other the Wake-on-Lan per se.

💡I would recommend you to check the following link where you will find information about the ports that TeamViewer needs to have open to work properly Ports used by TeamViewer.

While here is the 👉️ MANUAL for the correct configuration of Wake on Lan.

Let us know if it worked for you.

Best,

Unfortunately not, WOL just will not work from an outside network even though I have configured it as per the manual. TeamViewer however does work perfectly when the target PC is powered on.

In the end I found a workaround by leaving another device permanently powered on on my home network and connecting remotely to this device to send the magic packet as it seems this functionality doesn't work in TeamViewer.
