I frequently access computer 3 from computer 2. If I block port 22 I will have to use another on, correct? If I do enable another one, what is to prevent a user on computer 1 from accessing computer 2 and then on to computer 3? What I want to accomplish is making it impossible to access computer 3 from other than computer 2 and then only if computer two is not being used as a slave from computer 1, or any other computer for that matter. Probably what I want cannot be implemented; however, I thought I would ask anyway. -- Carmel carmel_ny@hotmail.com
