Balanceamento de 3 links de 35 Mb da GVT - Modems Roteados

Boa tarde amigos,

Configurei o routeros 5.20 em uma máquina com 4 placas de rede (1 para rede local e as outras 3 uma para cada link de internet). Fiz a configuração do PCC ballance como demonstrado no vídeo do Gerônimo. Gostaria de saber se está tudo certo. Abaixo segue como está a configuração. Desde já agradeço a atenção de vocês.
Aproveitando, gostaria de saber se é possível configurar o webproxy junto com o load balance neste mesmo mikrotik?
