Unblocked Pages VS Blocked pages

What if I want my entire site to be unblocked but only have select pages blocked time to time? As soon as I activated the plugin all it did is block my entire site directing anyone who is not registered to the register page. I want to allow anyone to view the entire site but then have a members only list of pages that can only be accessed if you are a member. I plan to have roughly 50 pages total.
