Доброго времени суток, уважаемые коллеги

имеется Cisco 1812-J
c181x-adventerprisek9-mz.124-24.T2.bin

isp2 - основной
isp1 - резервный, переход на него по sla при отказе основного, плюс через него почта с сервера принадлежащего isp1. это работает

еще хочется через isp1 подключаться снаружи к веб-серверу и к серверу pptp. неполучается.

причем на 2801 c2801-advipservicesk9-mz.124-24.T1.bin с аналогичными настройками все ОК. а на этой не хочет.
