Thanks for the comment,

I used checkpoint as an example, because this is the product i am most familiar with. I sure have my complaints, and a share of all-nighters due do issues with their products.

What products do you prefer, open source or commercial?

Like pc_user said at digitalpoint, thanks for posting the article.

However, my counterpoint is that having used a variety of firewalling systems, checkpoint is my least desired option. Different strokes, for different folks and all that.
