How to block a path but not a node

I am using grid movement, and I am currently trying to set up a door that will block movement through it, but still allow a player to stand directly next to it. Is this possible? I currently have a door model with the collosion bix width at 0, but both nodes on either side of the door are blocked. The way it currently is set up a player can never stand next to the door on either side. Is it possible to just block the connection between two nodes but still make both nodes useable?
