Sharepoint 2013 alternative access mappings

I am running a test server that has SharePoint Server 2013 running on it.

My installation of SharePoint is a Farm installation instead of Standalone as I want to add an addition test server at a later stage.
I have created a single Web Application; created a basic Team Site Collection.
The team site has a url of http://srvint for internal usage.
I then later created and second Site Collection, also Team Site template, under the same Web App with a URL of http://srvint/sites/test. A third site was also created with Document Center template with a URL of http://srvint/sites/data

Each site has the other sites' links listed to make navigation between the sites easier, so basically each has:
Site 1   Site 2   Site 3

All works fine. I now want to make all the sites available from the internet.
I went to my App Management under SP admin and extended my Web App with a url of
I tested the link and it worked just fine, I was able to log into the home page and access Site 2 and Site 3 just fine, however, once I have clicked on Site 2 I am unable to click on Site 1 or Site 3 as the links that are showing refer to the internal URLs and not the external URL. So if I am currently on Site 2 and want to go back to Site 1 I receive a 'Page cannot be displayed' error as the URL it is trying to connect to is http://srvint which is the internal URL.

How do I fix this? Do the Alternate Access Mappings not apply to sub-sites? Does each Site have to be configured separately?

Please assist.

Make sure you are using relative paths in your links and not absolute paths. The links should be:

and so on.
