Por exemplo;
No firewall tudo que for udp para a saida, podendo ser nas tabelas OUTPUT e FORWARD você bloqueia. Deixe liberado o acesso a servidores DNS, porta 53 UDP.
No squid você pode bloquear sites de streaming, ou pode bloquear por mime type. Acho interessante você instalar o dansguardian + urlblacklist vai facilitar muito a sua vida.
Ou pode bloquear por mime-type. Exemplo:
acl x-type req_mime_type -i ^application/octet-stream$
acl x-type req_mime_type -i application/octet-stream
acl x-type req_mime_type -i ^application/x-mplayer2$
acl x-type req_mime_type -i application/x-mplayer2
acl x-type req_mime_type -i ^application/x-oleobject$
acl x-type req_mime_type -i application/x-oleobject
acl x-type req_mime_type -i application/x-pncmd
acl x-type req_mime_type -i ^video/x-ms-asf$
acl x-type2 rep_mime_type -i ^application/octet-stream$
acl x-type2 rep_mime_type -i application/octet-stream
acl x-type2 rep_mime_type -i ^application/x-mplayer2$
acl x-type2 rep_mime_type -i application/x-mplayer2
acl x-type2 rep_mime_type -i ^application/x-oleobject$
acl x-type2 rep_mime_type -i application/x-oleobject
acl x-type2 rep_mime_type -i application/x-pncmd
acl x-type2 rep_mime_type -i ^video/x-ms-asf$
