4.3. Public web interface
From open-support.info
In addition to the web interfaces for agents and customers, OTRS also has a public web interface that is available through the FAQ-Module. This module needs to be installed separately. It provides public access to the FAQ system, and lets visitors search through FAQ entries without any special authorization.
In our example, the public web interface can be reached via either of the URLs below: http://www.example.com/otrs/faq.pl , http://www.example.com/otrs/public.pl
