Hi,
1. You don’t need to import Font Awesome via @font-face, it’s already included in the theme.
2. @font-face only imports a font, it does not apply it to anything. You would need to write CSS that specifies which element should actually use the font defined by @font-face.
Again, since your site is on an intranet, check in the development console of your browser’s inspection tools that the theme actually loads Font Awesome. This works perfectly fine, so it’s definitely something that is not loading, and I have a hunch it has to do with intranet and permissions.
Regards,
