ho problema su un Catalyst 3750 -12.2(25)SEE2-IP-BASE sul routing
tra le VLAN: in pratica non riesco ad arrivare tramite la porta FastEthernet1/0/1 verso il
router (192.168.1.1) da un qualsiasi host nelle 3 VLAN, mentra direttamente dallo switch ci riesco.
Premetto che le macchine nelle VLAN hanno come gateway l'indirizzo
della relativa interfaccia VLAN del Catalyst, infatti riesco a pingare host
di altre subnet, le interfacce VLAN del Catalyst ed anche la porta FastEthernet1/0/1 collegata al gateway.
Ecco la mia configurazione.
