con la nueva version 2.1.2, las reglas de salida, no las esta respetando,
lo que me indica que mejor instalare la version 2.1.0 que es mas estable, y que si funciono, en su momento.
Un punto a tener en cuenta son los cambios respecto a las reglas/policy routing entre las versiones 2.0.x y 2.1.x ;) como lo menciona @phil.davis en este post (si buscas por el foro, vas a encontrar mas posts haciendo referencia al tema)

Do you have policy-routing rules? (i.e. rules that specify a gateway)
The behavior of those has changed. In older versions, extra pass rules were automatically put in to allow "local" traffic to be passed to the normal routing table. Now in newer versions (2.1 and later), policy-routing rules do as they say, if you policy-route everything, then everything goes out the specified gateway. Often this is the reason for simple "local routing" to stop working on an upgrade like this.
Add rule/s before the policy-routing rules to pass traffic between "local" subnets, with no gateway specified.
