Добрый день всем!Достался мне в наследство шлюз с FreeBSD и 1С за ним. Я предпочитаю ipfw, а тут - pf. Пожаловался на днях 1С-ник, что не может связаться с какими-то сервисами. Через прокси почему-то 1С ходить не хочет - только в лоб, напрямую. Прописал я в секции rdr-nat по аналогии с другими такое правило:
nat on $ext_if proto tcp from $1C to {89.111.148.68, 89.188.115.186, 91.239.5.33, 91.239.5.113} port {80, 110, 443, 465} ->$ext_if
С 1С-а связи нет. :( Смотрю на внешнем интерфейсе и вижу интересную картину:
19:09:02.553514 IP XXX.XXX.XX.150.53269 > 91.239.5.113.443: Flags [SEW], seq 3411709067, win 8192, options [mss 1460,nop,wscale 8,nop,nop,sackOK], length 0

Вот третий по счёту пакет и рвёт сессию.
Я пытался явно в секции правил прописать разрешение на входящие от 91.239.5.113, прописывал и в начале секции, и в конце (по ман-у ведь, срабатывать должен последнее совпадающее правило) - не помогает. :(
Помогите - обо что "спотыкается" сессия? Второй день курю ман и интернет - не понимаю! :(
