Eu tenho um ASA5525-X com 9.1.2. Nele existem várias interfaces, mas principalmente eu estou olhando:
(sub-redes falsas)
- 10.0.0.0/24, nível de segurança 100
- fora de 10.0.200.0/24, nível de segurança 0
- DMZ 10.0.100.0/24, nível de segurança 50
Eu tenho um servidor DNS na DMZ, 10.0.100.1, que eu posso acessar de dentro sem problemas. No entanto, quero que ele apareça como 10.0.200.95 (não um IP real para este exemplo) para as pessoas na Internet. Eu tenho o que eu pensei que era necessário para que isso funcionasse, mas quando eu testo, os pacotes estão sendo descartados pela ACL padrão.
Partes pertinentes da configuração:

Alguma ideia?
