Hi,
You can't do hairpinning on a Cisco router. The only way to access it from inside would be either with its private address or by FQDN if there is a record for it on an external DNS server using the feature called DNS doctoring which is the default on Cisco routers.You could also use the hosts file on the clients to map the FQDN to the internal IP.

Hi Vipin,
You will be not be able to access the nated IP (public) from inside.
You must need to access that with the private IP.
This is because when you are going outside (to internet) through the same public IP and accessing the same is not allowed.

Hello Again Vipin,
Do you have any access-groups on the interfaces that you could share?
Are you trying to access a web server?
Please let us know the answer of those questions and if its possible please share the Running-config.

Hi,
Say, i have a server which is publically available. But the same thing i can't access from inside.
assume a webserver is that, and it can access publically as http://1.1.1.1:8080
but from inside of the organization i can't access the same page using http://1.1.1.1:8080.
This is what my doubt.
Why is this happening. i dont have the logic behind it. please advice.
Thanks
