You need to add the following types to an .htaccess/IIS:
AddType application/vnd.ms-fontobject .eot
AddType font/ttf .ttf
AddType font/otf .otf
AddType application/font-woff .woff
Updated .woff type from:
AddType application/x-font-woff .woff
(Thanks to @renadeen in comments below for pointing this out.)
