func_areaportal is a brush entity available in all 
Source games. It creates an areaportal, used to manage visibility in maps. When the portal is open it stops objects not visible through it from rendering; when the portal is closed it cannot be seen through at all.
These are not really brush entities. They are brush entities from a mapper/Hammer perspective, but by the time they reach the game, the brush is gone and this is, in effect, a point entity.
While it is not necessary for the entity to function, the texture tools\toolsareaportal (seen on the left) is intended to be used on areaportals.
Keyvalues
