Windows firewall ipv6 loopback issue

cn flag

I received it on my windows firewall log: DROP TCP ::1 ::1 53264 47001

I tried to add ipv6 ::1 or any other ipv6 loopback address to the firewall rule but received only the message below: An unspecified, multicast, broadcast and loopback IPv6 address was specified windows firewall.

I found some same question in https://github.com/falahati/WindowsFirewallHelper/issues/8 Where was indicated that : "This is a Windows Firewall limitation. You can not specify any loopback, broadcast or multicast IPv6 address."

What should I do?

Dropping localhost traffic is a great way to break your computer's services. Don't even make the attempt.

@MichaelHampton thank you for the information about it, but how I may add to the exceptions ipv6 loopback IP address to the windows firewall rule? p.s. It is on my VM

That's very strange because nothing should be blocking ::1 anyway.

@MichaelHampton I have a windows firewall rule which configured as: allow only 64000-65535. The DROP occurs on 47001 which is not included in the rule above. I create a custom rule configured as: allow IP any/any remote port 47001 and I didn't receive any DROP on windows FW. But I want to allow only IPv6 loopback address for this port and rule.Because request comes from ::1 which is IPv6 loopback address. P.S. the DROP coming from 127.0.0.1 and ::1.

@MichaelHampton above comment wrong. I checked again. I still receive DROP on firewall log. Only when IP any/any and port any/any I don't receive any drop.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
