Hi,
I'll have to re-create the diagram in Visio, it was originally made in Gliffy although my account seems to have lost that particular image.
Unfortunatly configs are quiet large, and it would take a considerable amount of time to sanitize them for posting, so if we can avoid that, that would be ideal.
I would suggest the biggest key piece of information (which maybe isn't well enough shown in the above diagram). is that at a Layer 2 perspective, the machines are connected on the same network, but with different subnets.
