Доброго времени суток.
Столкнулся с такой проблемой:
Есть сетка 10.0.1.0 класа С есть шлюз на ФРЕ на котором установлено 2 ИР с даной сети. При попытке установить алиас например 192.168.1.1 (клас С) через некоторое время, примерно пол минуты, сеть (сетевуха локалки) отваливается намертво (пинги не ходят, файрвол непричем не работает как с включенным так и с выключенным, сетевухи менял - результат тот же) причем инетовская (интегрированая на материнку) работает нормально. Попитка посмотреть sysctl -a |grep arp вызвала Кернел Паник
Из софта установлено: POSTFIX, SQUID, DBMAIL, AMAVIS, APACHE22.
как файрвол используется PF (на внешнем интерфейсе), IPFW (на внутренем, тольно разграничивает полосы, в конце всеразрешающие правило)
Кто сталкивался с подобным помогите, замучался уже искать.
