pero viendo en mangle no marc nada en http todo es marcado en balanceo ya que son las primeras reglas y viendo en ip/firewal/conection solo muestra las coneciones con marca uno, dos, tres, curtro, cinco las marcas del balanceo y nada de http y dns
PD: este server no hace web proxy
podria alguien ayudar y ver donde esta el error
