[support] Get all nodes in relations with

Hi list, I use CCK noderelation to link 2 different contents types. I have content type A. I have content type B with a nodereference to a content type A node. When I visit content type A I want to have a block with content type B nodes in relation with this content type A node. What sort of relation and arguments I must use in my view. I find many exemples to have the reverse (when I'm on type B, list all type A) but it's not that I want. Thanks in advance for your help.
