If you use the same name internally as externally, the internal DNS will not
be able to resolve any names in the external DNS that are not specifically
created or delegated from the internal DNS to the external DNS.
There fore you will need to add the records to the internal DNS such as www,
mail, or etc. Also you will not be able to access an external site by using
only the domain name such as http://domain.com this is why I do not suggest
people use the same name internally, I usually suggest going to a third
level name such as mydomain.domain.com. This prevents these internal
conflicts.
