    Windows firewall blocks ipv6


    I use the newest windows 10 and have both ipv4 and ipv6 addresses on my pc. When I make a outbound rule for blocking some ipv4 addresses, I can't visit any ipv6 websites. The browser says "Your Internet access is blocked". When I delete the rule, everything is ok. I think a recent windows update make this, because a week ago there was no problem.

    :)

    Windows Firewall blocking websites

    I have blocked IP addresses, e.g. 255.255.255.255, not URLs, e.g. somewebsite.co m.

    As far as unblocking, look at your Windows Firewall rules. Do you see anything that is blocked? If you do, click on the Scope tab and see what is listed there.

    Constant IPv6 pings to my firewall

    even disabled it will still have that listener.
    Most firewalls will detect local as well so that doesn't matter.
