    Router firewall ICMP risks and threats?


    Hello everyone I have found out, that my Router firewall has never blocked ICMP traffic. There is a lot of opinions online regarding ICMP, and whether it should be disabled or limited. So far I have found out, that it can exploited to monitor network traffic / I/O traffic (man-in-the-middle). It can also be exploited to carry and infect a PC system with malware. My questions / worries are: 1. If someone monitored my network traffic using ICMP, would HTTPS traffic then still be encrypted / unreadable? 2. Would my Windows Defender firewall block an attack / attempted malware infection via ICMP? 3. Would Malwarebytes (example) scan detect, if my PC system had been infected by malware via ICMP? 4. Are there other ways someone can access my PC system using ICMP, besides via malware infection? Thanks in advance for your answers And happy weekend! Best regards

    :)

    windows 10 firewall filtering icmp

    Amit(Kumar) did you even read what your link states? It is for developers that have access to programs and tools that most end users do not have. Your response is a class **** answer that floods these forums.

    Sorry elkido122, I am looking for answers to the same problem. Why do you feel that your IPV6 is limited to your ICMP rules? Are you basing it solely off these ipv6test type websites? IPv6 test - IPv6/4 connectivity and speed test

    I feel as if I have setup my system perfectly for IPV6 but when I hit that site it says my ICMP is being filtered and shows up yellow. I have allowed ICMP through my router and I have allowed it through windows firewall as well. I still get the same result,
    so I am at a loss. Let me know if you find an answer.
