Cat3560-48 подключен портом Fa 0/5 (vlan4) к WAN через межсетевой экран, а через Gigaбитные интерфейсы подключен к Cat3750, который своими другими гигабитными интерфейсами соединен с остальными свичами (Cat3560) локальной сети. Возникла задача - создать на портах Fa 0/13-15 основного коммутатора Cat3560 изолированный от всей остальной локальной сети вилан (VLAN 35 ip 210.32.35.0/24), из которого были видны только внешние сети в WAN. Почему то удаленные хосты, находящиеся за пределами локальной сети, видны только из коммутатора Cat3750, но не видны из Cat3560-48 и, соответственно, не видны с компьютеров, подключенных к его портам 13-15. Почему так, ведь пакеты в WAN идут через этот коммутатор? Кто может подсказать- где что не так? Спасибо! Конфиг Cat3560-48:
