How to enable ICMP v6?

[cliff62 0]

Hello,

In https://ipv6-test.com/  web site, I saw that there is a filtering for ICMPv6. How can I solve it in Eset Internet Security 15.0.21.0? (Windows 10 64bit)

This ICMP issue does not occur when I connect to Wi-Fi with my iphone.

ICMP (v6) is allowed only in the trusted zone by default:

We don't recommend changing these default settings.

I have used this same web site on occasion to verify IPv6 connectivity. I also receive the same score as you along with same message about ICMPv6 filtering. Note the message states both "router and firewall" as possible sources.

Most routers also contain a firewall and are by default, filtering ICMPv6 traffic. As such, assume the source is the router's firewall and not the Eset firewall. I also believe the message displayed is bogus. If there were ICMPv6 issues, DHCPv6 resolution to allow IPv6 network traffic and the like would be failing.

There must be something wrong with Windows or Eset firewall. I don't know.

When my mobile phone (İphone) connects to Wi-Fi (Tp-link Archer C80),  there is no ICMP filtering problem (18/20 score)

If you still believe EIS firewall is the issue, temporarily disable it. Verify in Windows Security Center that the Windows firewall is active; it should be.

Now go to the web site and observe if the score is the same and the ICMPv6 note appears. If it does, the Eset firewall is not the source of the issue. Finally, re-enable Eset firewall.

I disabled EIS firewall and made the ipv6 test again. (windows firewall didn't get active automatically)

Result is below.

You have to permanently disable the Eset firewall; not just pause it, to activate the Windows firewall.

As such, I performed this procedure for you and below is the result. With the Windows firewall active, the IPv6 test results are the same as when the EIS firewall is active. Therefore, I conclude that it is my router's filtering of IPv6 network traffic that the web site finds issue with. And, I again state the web site output is bogus.

I will state that the recommended test for IPv6 connectivity is here: https://test-ipv6.com/ . If you score 10/10, you have no IPv6 issues.

Finally, this TP-lInk forum posting is most informative: https://community.tp-link.com/en/home/forum/topic/215396

When the router's IPv6 SPI Firewall is enabled and the https://ipv6-test.com/ test is performed, the ICMPv6 problem text is displayed. When the router's IPv6 SPI Firewall is disabled, the score is 19/20 with no ICMPv6 problem text displayed.

Bottom line - the router's firewall is blocking un-stateful ICMPv6 traffic as it should.

Are you actually having any connectivity issues or problems? Or just concerned with the results of this questionable test the site offers?

Better to keep ICMP disabled or only enabled to Local Network, There is no need for opening ICMP and have your address pinged by bots if there is no need for it.

Unless you are offering some public service/server or something similar , other than that , it's better to keep it blocked.
