Доступ через циску (2811) на любой внешний сервис (из LAN в WAN, из LAN в DMZ, из DMZ в WAN - без разницы) идет с большим таймаутом. Поставил на внутренний интерфейс permit ip any any - тот же эффект.
Например, ssh 192.168.1.12 висит около 30 секунд до вывода приглашения, telnet 213.180.204.8 80 висит секунд 20, днс вообще не работает - видимо изза большого таймаута..

Если сессия установилась, дальше она работает без проблем. Например ssh после того как принял пароль работает дальше шустро, без тормозов.

Подскажите, в чем может быть дело?

Вот конфиг циски:
