Thanks for the help, when I tried the alias command on the inside interface I manage to ping the public NAT ip from internal but the thing is I still cannnot browse the website from internal. I browse the website from internal via its URL www.website.com(internal DNS resolve this as public IP) and it shows me "page cannot be displayed error", but if browsing it's private ip it works.
DO you have any advise what points I forgot to check.
Our network setup is like this: our Public DNS server is inside the DMZ zone, this DNS server also acts as a proxy server for internal(inside) users. The web servers are also sitting inside the DMZ zone. Even the DNS Server cannot browse the webserver URL.
I noticed that all cisco docs on alias follow the setup whereby the DNS is sitting outside the PIX.
