100% loss when trying to ping external IP assigned to PС

Question

I have external IP adress given me by my internet provider, for example, ip.ip.ip.ip on PC I'm using right now, however, when I'm trying to ping ip.ip.ip.ip using this PC I have "100% loss". I need it for remote "Wake Up" function.

I'm using Windows 10, "Private network", ZyXEl Keenetic Omni.

Answer 1

From the trace, I can see that the first hop was to IP address 192.168.1.1 which is surely your router. The next hop was to 88.200.185.179 which is a Russian address which I assume is in the network of your ISP.

To make such a loop work : PC -> router -> ISP -> router -> PC, you need a router that supports such a loopback connection. Evidently yours does not support loopback.

You need to make the ping from outside your local network, because the router cannot do it.

Note also that the static IP address given by your ISP is not that of your PC, but rather of your router.

Answer 2

If your router is configured for NAT, your PC address will be different from the public IP address. In addition, routers usually do not respond to WAN-side pings to avoid IP scanners. If you just enable Ping response on your router, it will be your router responding, not your PC. You probably do not want to use ping for wake-up. You can configure your router firewall port forwarding to forward some packets from WAN to specific LAN IP address.
