Players walk through a prop

I need some help here. Basically I want to block of a certain part of a map to non-vips but let the vips walk through it as if nothing is there. The only way I can think to do this is with a prop. Is there a way for some players to be able to walk through a prop and others not depending on there level? Or is there a better way to do this I don’t know of?

yessir

edit:

If this is a gamemode where everyone has access to noclip though, I would suggest using ents.FindInBox than dealing with props.

Thank you very much.
