How to block ICMP traffic to your VPN server on windows?

Question

VPN

I want complete anonymity online. I recently read on the Internet that a certain vulnerability:

Tunnel detection (two-way ping)
By starting a ping to the client IP, from our server side, you can find out the approximate length of the route. The same can be done from the browser side, XMLHTTPRequest pulls an empty page of our nginx. The resulting loop difference of more than 30 ms can be interpreted as a tunnel.
Of course, the routes back and forth may differ, or the web server slows down a little, but in general the accuracy is quite good.
The only way to protect yourself is to block ICMP traffic to your VPN server by properly configuring your firewall.

As mentioned above, you need to configure your firewall in such a way that it prohibits ICMP traffic to your VPN server. How to do it on windows?

The topic of anonymity on the Internet has already been discussed here many times. So, she's not there. Simply no, and everything cannot be :) Because your provider not only knows which servers you accessed, but also merges it to the right place (and not of its own free will - it is supposed to).
And banning ICMP for greater anonymity is like knocking out teeth so as not to be afraid of a drill :)
