Cisco 3825 на ней 4 FastEthernet interfaces
Есть линк Ethernet от провайдера.

Проблема
Всё прописанно но ничего не видно даже шлюз провайдера

Вот кусок конфига

interface FastEthernet0/0/3
switchport access vlan 4

interface Vlan4
ip address X.X.X.Y 255.255.255.224
ip information-reply
ip directed-broadcast
ip route-cache flow

Причём на физическом интерфейсе я вижу вход и исход пакеты а на Влане только исходящие

Подскажите плз в чём может быть дело?
