[Skybox has no collision, help?]

so i made a skybox in maya and when i upload it to secondlife i cannot walk through it even though there is an opening on one side, so i rezzed it again but this time by my feet and i was inside it, the problem is once inside i can walk through the walls and when i do this i cant walk back in.

Is there any way to add collision to my skybox once inside?

i have rezzed other skyboxes inworld and once inside they work fine, i cant walk through walls but my own made skybox does not have collision
