@Font face fonts only work on their own domain - @font-face fonts only work on their own domain

problem ：

I am trying to create a type of font repository for use on my websites, so that I can call to any font in the repository in my css without any other set-up. I am trying to create a font repository for use on my website , So that I can be in my css Call any font in the repository , Without any other settings .To do this I created a subdomain on which I placed folders for each font in the repository that contained the various file types for each font. So , I created a subdomain , A folder is placed on this sub domain for each font in the repository , It contains various file types for each font .I also placed a css file called font-face.css on the root of the subdomain and filled it with @font-face declarations for each of the fonts, the fonts are linked with an absolute link so that they can be used from anywhere. I also placed a file named... In the root directory of the subdomain font-face.css Of css file , And for each @font-face Filled @font-face Statement , Fonts are linked by absolute links , So that they can be used anywhere .

My issue is that it seems that I can only use the fonts on that subdomain where they are located, on my other sites the font does not show. My question is , It seems that I can only use the fonts on their child fields , On my other sites , The font does not show .Using firebug I determined that the font-face.css file was successfully being linked to and loaded. Use firebug I'm sure font-face.css The file was successfully linked and loaded .So why does the font not correctly load? So why aren't the fonts loaded correctly ？Is there protection on the font files or something? Are font files or other things protected ？I am using all fonts that I should be allowed to do this with, so I don't see why this is occurring. I am using all the fonts I should be allowed to use , So I don't understand why this happens .Maybe it is an apache issue, but I can download the font just fine when I link to it. Maybe this is a apache problem , But when I link to it , I can download fonts very well .

Oh, and just to clarify, I am not violating any copyrights by setting this up, all the fonts I am using are licensed to allow this sort of thing. Oh , To clarify , I set this without infringing any copyright , All the fonts I use are licensed to allow this kind of thing .I would however like to set up a way that only I can have access to this repository of fonts but that's another project. However , I want to set up a way that only I can access this font library , But this is another project .
