Hi Cisco Experts,
Kindly need your advice on the below;
Setup : Cisco ASA 5520
Any Traffic from any source pointing to Destination IP (Ex: 192.168.10.10:53) to be NATed (Destination Translated) to 172.16.10.10:53. The ASA will have route to 172.16.10.0/24 pointing to the Router's Gateway and the traffic will go outside
It should go out with Same Source IP and Translated Destination IP (From:192.168.10.10:53 to 172.16.10.10:53).
This sounds like Policy Based Destination NATing.
Your Valuable Suggestions are Appreciated.
Thanks a lot,

Hello,
You just need destination NAT.
Static(outside,inside) udp 192.168.10.10 53 172.16.10.10 53 netmask
255.255.255.255
This is assuming that your internal network is either 192.168.10.x or your
hosts are using the ASA as the gateway.
Hope this helps.

Hi Nagy,
Thanks for your response..
Let me be more specific..
My Host IP: 10.10.10.10 (Source)
My DNS IP: 192.168.10.10 (Destination)
IP to be Translated: 172.16.10.10 (Xlated Destination)
The actual IP address of the DNS is 172.16.10.10 and i dont my LAN users to see this IP. So, we use 192.168.10.10 for users and we translate that to 172.16.10.10, which will not be visible to users..
Hope you got it..
thanks

This request from inside my LAN should be

Hello,
The configuration I posted earlier achieves the exact same purpose.
172.16.10.10 will be appearing as 192.168.10.10 for all the internal hosts.
