Hola compañeros, tengo un problema con hotmail, en las maquinas que salen a traves del proxy transparente no me deja descargar ningun archivo adjunto, sea cual fuere la extension, y no he bloqueado archivos por extension o por algun modo.

 

les paso la config del squid

 

visible_hostname anubis.ipp.edu.pe
