Hi,

This is called hairpinning and it's not implemented on Cisco enterprise routers.

One workaround is to use DNS doctoring: provided you have a public DNS with the record for your public IP then you can access it from inside by fqdn.

Alain's correct

Maybe you have 2 copies.

1 Production for public

2. Development for your internal access to update /make changes etc. This is more recommended method

    is normally suited in hosting environments

I don't get it. If you are trying to access an internal server from the internal network what brings you to the router?
