Saya memiliki ASA5525-X dengan 9.1.2. Di dalamnya ada beberapa antarmuka, tetapi terutama saya sedang melihat:
(subnet palsu)
- di dalam 10.0.0.0/24, tingkat keamanan 100
- di luar 10.0.200.0/24, tingkat keamanan 0
- DMZ 10.0.100.0/24, tingkat keamanan 50
Saya memiliki server DNS di DMZ, 10.0.100.1 yang dapat saya akses dari dalam tanpa masalah. Namun, saya ingin ditampilkan sebagai 10.0.200.95 (bukan IP nyata untuk contoh ini) kepada orang-orang di internet. Saya memiliki apa yang saya pikir diperlukan untuk ini berfungsi, tetapi ketika saya mengujinya, paket-paket sedang dijatuhkan oleh acl default.
Potongan konfigurasi terkait:

ip address 10.0.100.254 255.255.255.0
