Switching VANS - where do i set the parameters to RECEIVE data

We’re using webMethods 6.5, and are currently switching our VAN. In order to send documents, I was able to go to:
Tools > Registry > Public Queues and edit the queue we have for our VAN so I could change the inputs to the “Delivery Service” (See attached screenshot)

When I schedule the queue for delivery, the documents are sent. But documents in the external VAN folder for US are not picked up.

Where do I find the settings for this?

PS - Mods, I posted the same thing in the wrong subsection (http://tech.forums.softwareag.com/techjforum/posts/list/0/57950.page#215832)
