Проблема с IPv6, периодическая потеря пакетов



  • Здравствуйте, дамы и господа!

    В англоязычном форуме никто ничего не написал, может хоть земляки помогут :)

    Я практически новичок в IPv6, но достаточно хорошо понимаю IPv4.
    Итак, суть проблемы: роутер периодически перестает отвечать на пинг из локалки, причем даже локального интерфейса! IPv6 сеть получена от he.net (думаю, как и у большинства). С роутера все работает нормально. Доступ в Интернет есть, но, думаю, понятно, насколько стабильный.

    Версия Pfsense: 2.3.2-RELEASE

    Насколько я вижу, роутер перестает отвечать после "ICMP6, neighbor solicitation" запроса без ответа.

    Какие идеи?
    Заранее спасибо!
