It is unfortunate that there is no documentation to explain how to use the Kunena Discuss plugin. The "best" that I can find for you are two general topics:

I gave that open forum pubic accessibility. In my Kunena configuration I have "Allow Guests to Post/Write" on Yes. Right now only registered users can post comments.
There are a couple of things you need to do before guests can post on your forum. First of all, as 810 has mentioned, you need to modify the forum category permissions for the categories where the comments are collected to give
Guest the ability to
reply to topics. Secondly, and most importantly, you need to disable Joomla caching;
if caching is enabled guests cannot use the Kunena Discuss plugin to comment on your articles
.
However, as 810 has already written, if visitors can use the form generated by
Kunena Discuss plugin (when they view the articles/blog) they can also post replies to other topics (in the same category/categories) where they have permissions.
