Zone transfers don't work by file name, they work by domain name.  ns2
connects to ns1 and says "Send me all the records in the domain.com zone."

ns1 gets the address that this request comes from, and searches its list of
views.  If the address matches the internal view, it sends the records from
named.internal; if the address matches the external view, it sends the
records from named.external.

If you want your slave to be able to serve both views, it needs to have two
addresses: one that matches the external view, and another that matches the
internal view.  Use the "transfer-source" option within its views to force
it to use the appropriate one when it's pulling the records.
