func_portal_bumper is a brush entity available in 
Portal series.
 Class hierarchy

Entity description
It tells Portal to 'bump' portals that cannot open inside it away. Use it when a portal-proof surface runs directly on to a portal-friendly one.
While having this is not absolutely necessary, it does make your puzzles much more user friendly. You don't need to use one if there is an angle in the surface (e.g. the corners of a room).
Note:Each func_portal_bumper must stick at least two units out from the surface.Usage
Not using a portal bumper
