Forum Threads Not Viewable to Guests

[dvduval]

I set this a long time ago and can't seem to find the setting. I have a forum/node where when you are a guest you can see the name of the forum, but the threads are not viewable (non-public). I want to switch back and allow all the threads from this forum to be indexed, but I can't seem to find the setting in the admin panel.

And I mean just one node has this problem.
