Install works fine but can only access app from localhost

Dear Fat Free CRM Users

Thanks for this wonderful project.

I am able to run the project with the following command and monitor normal output:

% ~/fat_free_crm % s rails server  -p80                                                                           =================================================

=> Booting Thin

I can then run something like:

% w3m http://localhost

And then I can run the app in text mode:

=============================================

I see no errors but am limited by the text browser of course at a point.

I cannot access the site from another machine in development mode.

If I run the app in production mode then I *can* access the app from an external machine but the app gives an error:

================================================

=========================================================

When I first succeeded to run the application, I remember that it worked on the default port 3000, however I find that I cannot access it with the (text) browser on that port and have to run it on port 80 now.

I cannot understand the complete process of installing for a access via a specific domain, subdomain or subdirectory. Or whether there is an setup of apache required. 

I would very much appreciate some suggestions on how to solve this issue.

Many thanks

Eric
