É comportamento tipico de burla o proxy certo?

Alguma sugestão de como resolver?

veja que... a porta eh 443 ... http-ssl .. precisa verificar se ele nao esta acessando algum servico que use http-ssl
voce pode fazer assim:
acl sslconn method CONNECT
acl usuario_restrito src 192.168.105.168
http_access deny sslconn usuario_restrito
se nao funcionar inverta a ordem
http_access deny usuario_restrito sslconn
fazendo isto voce proibe ele usar seu proxy para conectar diretamente em outros proxies..

Legal Alexandre, vou colocar isso aqui para todos, ou pensar em alguma forma de criar um grupo de usuário porque o pessoal do financeiro usa essa porta e não posso bloquear.
