Como bloquear o UltraSurf

UltraSurf é um programa proxy que trabalha em conjunto com seu navegador para permitir que você navegue por qualquer site na internet, burlando firewalls e servidores squid. Muito usado por alunos de universidades e funcionários que possuem bloqueio de sites, ele é o terror dos administradores de rede, pois sempre acha uma brecha que permite uma navegação mesmo em sites bloqueados.

Mas há uma maneira de bloquear o UltraSurf através de algumas regras adicionadas no iptables do seu servidor Linux.
