Доброго всем времени суток.

Есть две Сisco1760, между которыми нужно наладить связь, есть ethernet'овские модули WIC-4ESW для каждой. Хочу вутренние сети "повесить" на модуль, а ethernet порт хочу оставить для настройки по Web и чтоб Cisc'и между собой связывались. Получилась у меня такая настройка:

version 12.4

!
ip http server

line con 0
line aux 0
line vty 0 4
!
end

На втором маршрутизаторе настройки такие же, только адреса соответственно
192.44.4.101 255.255.255.0
10.1.1.1 255.255.0.0
20.20.1.1 255.255.0.0

И проблема, собственно, в том, что я не могу запинговать маршрутизатор из внутренней сети, т.е. не могу достучаться на 20.21.1.1, а если со второго маршрутизатора (20.20.1.1) делать ping на первый (20.21.1.1), то все хорошо. Подскажите пожалуйста, что не так!
Заранее спасибо.
