Can't Access My website hosted on my internal webserver behind a Cisco Router

ahmedahmedahmedahmed Posts: 41Member ■■□□□□□□□□
Hello,
I have a website hosted on my .52 webserver, port 80 and 53 have been opened. I can access the website from the internet by using its public IP address but not its name (www.aaa.com).

Below is my configuration I have broken down my configuration into three phases
1) NAT for two ISP's : one Primary and one for backup.
2)Zone Based Firewall (outside to inside)
3)Zone Based Firewall (inside to outside): done using CCP
My Nat is working perfectly fine, I configured the Outside to Inside Zone opening up the relevant ports, and all the right ports are opened, I used CCP to configure the Inside to Outside Zone because I am not sure of all the ports that would need to be opened and is pretty straight forward with CCP.

-My internal DNS server is 10.0.0.1 and configured properly because it is currently working with a proprietary Firewall.
-From inside to outside everything works fine.
-I can ping my DNS server from my router, I have opened port 53 for my DNS server on ZBF.
-I can Ping my website on my 10.0.0.52 webserver from my Router using its name ie ping www.aaa.com and it shows it to resolve to the correct Public IP and ping successful.
-From the Internet I can access the website from the external Ip address http://216.140.140.4 (10.0.0.52- 216.140.140.4) but not as http://www.aaa.com.
however cant get it with its name
-I dont have a Nat entry for my internal DNS server however I have opened up Port 53 for it on Zone Based Firewall.

Now I dont understand how to provide the static Translation as I dont need the DNS server to really access the Internet, or am i getting something wrong?
Please would appreciate your help.
Bellow is my configuration.

    Hey man, so you said you can reach the website by IP but not by name. Did you validate your DNS configuration? Because you said the IP stuff is working there is not a lot of reason to look toward your router. At least not until you know your DNS is correct.

    Ya I got it working by creating a Static PAT to my DNS server.
    Thanks
