I am configuring an ASA 5510 with firmware version 8.0(4). In my setup, I have a routable IP assigned to the outside/wan interface (security level 0) and 192.168.0.0/255.255.0.0 block on one interface (security level is 100 and name is inside) and a 10.10.10.0/255.255.255.0 block on another interface (security level is 10 and and name is guest_wl).
I have a server (IP is 192.168.50.10 and it is in the 192.168.0.0 block) that is accessed from outside as well as from the 10.10.10.0 block on tcp ports 993 and HTTPS. The DNS servers are outside and the hostname is assigned to the outside interface IP of the ASA. The outside interface IP is mapped to the server's IP using static PAT:
static (inside,wan) tcp interface https 192.168.50.10 https netmask 255.255.255.255 dns
static (inside,wan) tcp interface 993 192.168.50.10 993 netmask 255.255.255.255 dns
Access from ouside on both ports works fine. And I have setup the rules for accessing the server from the 10.10.10.0 block and I can access the server using the IP (192.168.50.10) address. But, when I try to ping the hostname of the server from a machine in the 10.10.10.0 block, it resolves to the outside interface IP. According to the documentation on DNS doctoring, I should be resolving to the internal server IP.
I would greatly appreciate any ideas on what I could have done wrong here. Thanks!
