Tengo un ASA5525-X con 9.1.2. En él hay varias interfaces, pero principalmente estoy mirando:
(subredes falsas)
- dentro de 10.0.0.0/24, nivel de seguridad 100
- fuera 10.0.200.0/24, nivel de seguridad 0
- DMZ 10.0.100.0/24, nivel de seguridad 50
Tengo un servidor DNS en DMZ, 10.0.100.1 al que puedo acceder desde adentro sin problemas. Sin embargo, quiero que aparezca como 10.0.200.95 (no una IP real para este ejemplo) para las personas en Internet. Tengo lo que pensé que era necesario para que esto funcione, pero cuando lo pruebo, los paquetes están siendo descartados por la acl predeterminada.
Piezas de configuración pertinentes:
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

¿Algunas ideas?
