  Hello,

  you have chosen a bad decision with using the the same external and internal domain name. This result in split brain DNS requirements, see here about details from DNS setup:

  When query is sent to the DNS server to resolve a name the server first looks in its cache. If the name isn't in the cache and the DNS server holds any zones, it looks in those zones to try to resolve your request. The server goes to a forwarder or to the Internet only if it can't answer the request from its cache or its zones. DNS server favors the information in its zones over information it can find on the Internet.

  In your case since the internal and external domain name is same the query gets resolved internally and never goes to the internet. A possible workaround would be to add an entry for the external site to the hosts file on the each server (C:\Windows\System32\drivers\etc) but that is not a good business solution. If you're in an initial testing stage I suggest you rename the internal domain and start over.
