natural ranged attack is generally considered a natural, non-magical attack (for example, being able to fire a porcupine-like quill at an opponent); even where it is interpreted as "breathing fire", the attack is considered non-magical.
However it is entirely at the GM discretion ...
Note that generally the ability to perform such an attack will make you look a bit freaky ... (so you would have those porcupine quills at least on your back of=r chest or the back of your hands, etc).
