Community Support Forums

I'm trying to let all users have access to certain forums but restrict certain forums to just my paid members. I have tried with URI protection like (forums/forum/members/) but having no success. I can shut down the forums completely unless they are a free member or paid member but I want anyone to have access to the main forums page but than add restrictions from there...Is this possible?

Having no luck with the URI protection...thanks.

Sorry for taking so long, just noticed this thread.

Could you share some of the URLs to the forums you want to protect? You can change the domain name, of course, I'm interested in the rest.
