Some pages not protected with membership 2

Hi,
I have some pages that i have protected with membership 2 but they are still accessed by guests on the site.

I have protected the 'forums' page but when a guest clicks on the link for that page they get access to it and not the protected content page. I have made the forums private so they won't show but i don't want guests being able to access the page at all - i want them to see the protected content page.

I have protected it from the main menu at the top, but if you type in the website url/forums the guest can access the page.

I have also tried to protect it using the protect url option but its still not protected.

It also is the same for the classified page/s.

Can you help?
