 It sounds like you took the origin brush and made it a func_door_rotating without the rest of the brushes of the door.
 Select the origin and ALL the door brushes and use Ctrl+T to fix it. It will tie them all together into the func_door_rotating.
 
 To make a one-way door you need to use a func_button or a trigger_multiple that is only accessible on one side of the door.
 
 I would give the door a name like happydoor and make a big trigger_multiple on one side and target it at happydoor. When the player steps into the trigger_multiple the door will open.
 
 Triggers are invisible in game.
