Chances are that you are running into a problem with either Kerberos or
NTLM authentication, both of which are represented by Windows Integrated.
Kerberos will have a significant problem if the machine trying to connect
to the resource is not a member of the same domain as the web server. This
would explain why it works fine inside your LAN and from some other
locations; most likely remote machines that are members of the domain.
If you are not using Kerberos then you are using NTLM which will work
across a few types of proxies and routers, but not most. Generally it is a
fluke when NTLM works across the Internet due to all the routing and proxy
hardware and software involved.
You have two real options for accessing the directory from the Internet,
Basic and Digest.
If you want to use Basic I would also recommend configuring SSL on the
directory so the password and user ID (which are sent in effectively clear
text) are protected from prying eyes.
If you want to use Digest please see the following article for instructions
on how to configure it properly:

Hope this helps.
