    Hello,
    I've discovered an annoying problem in Plesk 11.
    When you register a .fr domain name, you need to have a Success ZoneCheck at http://www.afnic.fr/fr/produits-et-services/services/zonecheck/formulaire-complet/

    The test fail because the server didn't answer to ICMP IPv6 requests.

    Error: The server does not listen to or does not answer in UDP on the port 53 (on the IpV6)

    My question is: How to open port 53 on IPv6 for ICMP requests ?

    This is functional with IPv4 But not IPv6.

    There are some rules in the Plesk Firewall, but it seems not working at all.

    Thanks for your help !

    Same problem was reported but no answers to fix it.

    May 2012 - It seems as if there's a problem with the IPv6 firewall ICMPv6 default settings : http://forum.parallels.com/showthread.php?t=259849

    May 2011 - The IPv6 firewall rule for the Ping service is not getting correctly translated to an ICMPv6 rule in ip6table : http://forum.parallels.com/showpost.php?p=445697&postcount=41

    update: it seems to be a problem related to isconfiguration of ipv6 addresses and missing ipv6 gateway....

    I ad to
    1)go to ip list page, click on "reread IP", then found all ipv6 misconfigured, click repair for each of them
    2)open ssh and add default gateway

    then it started to work again
