How to turn on the power (or wake up) on a PC using WakeOnLAN or others via the Internet?

Question

network hardware

There is a home PC and a Tenda W268R router without a white IP. WakeOnLan only works if you are on the same network. Is it possible to somehow tweak the firmware of the router so that it connects to some server on the Internet, and from another local network I can send commands to the router through this server, which in turn to the PC network card. Maybe somehow you can raise a VPN or SSH on this router or something like that?
To be honest, I’m still thinking about the perversion of taking an arduino + GPRS + GSM + relay and, by sending SMS, close the relay on power ....

Answer 1

You need to dig towards DDNS for dynamic IP, and you also need to forward ports for a specific machine in a subnet with an IP address. And, if necessary, to manage your router, set up remote access to it from the world.

Answer 2

On this device, as far as I understand, you can run openWRT, and on openWRT you can write different scripts, like this . You just have to change the log parsing to some kind of interaction with a remote server (using wget or curl).

Answer 3

Ip gray or just dynamic? If three times, then you can configure ddns and connect to the router from anywhere

Answer 4

IP gray and dynamic
Thank you very much for the advice but I ran into difficulties:
1.) in the standard firmware of the DDNS router there is only in Chinese 88ip.cn and 3322.org I tried it on 88ip.cn, I got a domain, but the domain does not ping and the web does not enters it
then when the computer is turned off, I go, for example, to https://www.depicus.com/wake-on-lan/woli , I prescribe the MAC address of the PC network card, the demon101 domain. 88ip.cn left the mask 255, tried the port and 7 and 9 I press wake up but nothing comes out 2. ) I understand
openWRT:https://wiki.openwrt.org/toh/tenda/w306r I dismantled the router and my version 3.0 has 2 broadcom bcm5356 chips .. and winbond w9864 ... in general, the firmware is "openwrt-15.05-ramips-rt305x-w306r-v20 -squashfs-factory" is not set by web download. I’m thinking how to flash through the u-boot bootloader itself or find the firmware I need
