Ho un ASA5525-X con 9.1.2. Su di esso ci sono diverse interfacce, ma principalmente sto guardando:
(sottoreti false)
- all'interno 10.0.0.0/24, livello di sicurezza 100
- fuori dal 10.0.200.0/24, livello di sicurezza 0
- DMZ 10.0.100.0/24, livello di sicurezza 50
Ho un server DNS in DMZ, 10.0.100.1 a cui posso accedere dall'interno senza problemi. Tuttavia, voglio che venga visualizzato come 10.0.200.95 (non un vero IP per questo esempio) per le persone su Internet. Ho quello che pensavo fosse necessario per far funzionare tutto questo, ma quando lo collaudo, i pacchetti vengono eliminati dall'acl predefinito.
Pezzi di configurazione pertinenti:
interface GigabitEthernet0/0
nameif outside
security-level 0
ip address 10.0.200.194 255.255.255.192
interface GigabitEthernet0/6
nameif DMZ
security-level 50
ip address 10.0.100.254 255.255.255.0
interface GigabitEthernet0/7
nameif inside
security-level 100
ip address 10.0.0.254 255.255.255.0

Qualche idea?
