The Font Awesome icons used in 2.3 and forward are located in /usr/local/www/vendor/font-awesome
we can (and do) use the GUI when there is no WAN connection
Edit: any chance you're running a browser plugin that is blocking the font-awesome fonts?
FA started adding logos and stuff to the fonts and there are 3rd party lists you can use that are more aggressive and font-awesome is in some. https://github.com/FortAwesome/Font-Awesome/wiki/Troubleshoo...
