You are including the font file relatively, you need to include it absolutely. Relative paths will always append the path to the current path, eg if you are in /d/123213-foo the fonts/IRANSansWeb.eot is appended to it like so: /d/fonts/IRANSansWeb.eot. What you need to do in that font-face declaration is prefix the path with a /:
@font-face {
font-family: iransans;
font-style: normal;
font-weight: normal;
src: url('/fonts/IRANSansWeb.eot');
src: url('/fonts/IRANSansWeb.eot?#iefix') format('embedded-opentype'),
/* IE6-8 /
url('/fonts/IRANSansWeb.woff2') format('woff2'),
/ FF39+,Chrome36+, Opera24+/
url('/fonts/IRANSansWeb.woff') format('woff'),
/ FF3.6+, IE9, Chrome6+, Saf5.1+*/
url('/fonts/IRANSansWeb.ttf') format('truetype');
}
Make sure the fonts are in public/fonts.
