Bom amigos após testar varias soluções de balanço cheguei a esta configuração,Considerando que funcionam bem.
Esta configuração também permite fallover no caso de qualquer uma dos Links cair ou Desligar, A primeira seção das regras de mangle são feitas explicitamente para permitir conexões de entrada como Winbox / ftp / http / etc, basicamente, qualquer coisa que você deseja transmitir para um usuário interno irá funcionar correctamente e ser enviadas de volta o mesmo link (incluindo qualquer coisa adicionado por regras upnp).
Antes de mais nada gostaria de ressaltar pra nao usar copiar e colar,entender as regras e adaptar as suas necessidades e fundamental para um bom funcionamento do sistema.
