Designate a inside and outside side to the wall, or for each panel.

Any creatures, objects, attacks ,spells, or other effects from the outside of the wall are blocked by the wall, while attacks ,creatures, objects, spells, and effects from inside the wall can pass through it easily. a creature from outside the wall cannot see inside of it but a creature from inside the wall can clearly see things outside the wall.
